[PATCH 4/4] configure: manage libkmod.pc.in and version.py.in via AC_CONFIG_FILES

[Emil Velikov <emil.l.velikov@gmail.com>]

From: Emil Velikov <emil.velikov@collabora.com>

Replace the manual sed command, build rules and dist/clean for using
AC_CONFIG_FILES. It does the exact same thing, with an added bonus...

Currently we're missing version.py.in in the EXTRA_DIST. Thus a simple
"touch Makefile" should retrigger the regeneration of version.py. Which
would presumably fail, since the input file isn't in the distribution
tarball.

Feel free to compare the diff between the old/new "make distcheck".
Cannot realistically add that here as it seemingly confuses the hell out
of git am.
