Plan9/mkfile: Don't build mktags nor generate blocktags

Browse Source 
Remove the obsolete workaround of directly building mktags
and running it in Plan9/mkfile. The upstairs configure.sh
and make no longer fails to generate the blocktags file.

Update Plan9/README.md generally.

# *Discount* Markdown compiler on Plan 9
## Build
### One line
% mk install
% markdown -V
markdown: discount X.Y.Z GHC=INPUT
### Stepwise
% CONFIG='--with-tabstops=7' mk config
% mk
% mk test
% mk install
% markdown -V
markdown: discount X.Y.Z TAB=7
markdown: discount X.Y.Z TAB=7 GHC=INPUT
### Configuration
To select features and extensions, `--with-tabstops=7` may be replaced by zero or more of:
See `../configure.sh` and `../pgm_options.c` for other config options.
* `--enable-pandoc-header`: Use pandoc-style header blocks
* `--enable-superscript`: `A^B` becomes A<sup>B</sup>
* `--enable-amalloc`: Enable memory allocation debugging
* `--with-tabstops=`*N*: Set tabstops to *N* characters (default 4)
* `--enable-alpha-list`: Enable `(a)/(b)/(c)` list markers
* `--enable-all-features`: Turn on all stable optional features
### Other *mk*(1) targets
* `clean`: Delete built objects from source directory.
* `nuke`: Delete built objects and generated configuration.
* `install.libs`: Discount includes a C library and header.
Installation is optional. Plan 9 binaries are statically linked.
* `install.man`: Add *markdown* in manual sections 1, 2, and 6.
* `install.progs`: Extra programs. *makepage* writes complete
XHTML documents, rather than fragments. *mkd2html* is similar,
but produces HTML.
* `installall`: Do all `install*` targets above.
* `uninstall`: Remove anything added by `install*` targets above.
## Notes
1. This is not a port from POSIX to native Plan 9 APIs. The supplied
`mkfile` merely drives Discount's own `configure.sh` through Plan 9's
*APE* environment (in *pcc*(1)) to build the Discount source, then
copies the result to locations appropriate for system-wide use on
Plan 9.
2. There are a few other *mk*(1) targets:
* `install.libs`: Discount includes a C library and header.
Installation is optional. Plan 9 binaries are statically linked.
* `install.man`: Add manual pages for *markdown* in sections 1, 2, and 6.
* `install.progs`: Extra programs. *makepage* writes complete XHTML
documents, rather than fragments. *mkd2html* is similar, but produces
HTML.
This is not a port from POSIX to native Plan 9 APIs. The supplied
`mkfile` drives Discount's own `../configure.sh` and the `../Makefile`
it generates through [Plan 9's ANSI/POSIX Environment (APE)][ape-paper]
(in [*pcc*(1)][pcc-man]) to build the Discount source, then copies
the results to locations appropriate for system-wide use on Plan 9.
