mingw: build change
- removed internal.h include to be on the same page with *nix build,
which dropped it for some reason.
(internal.h included purple's config.h which in turn defined own PACKAGE_*,
which conflicted with Makefile.mingw defines for the same.)
- not consuming purple's config.h any more through inherited defines in
Makefile.mingw
NOTE for *nix optimizations:
sipe-common.h which now contains defunition G_GNUC_NULL_TERMINATED should (!)
preceed purple's includes, not only sipe includes, for mingw build to
be successful.
