By ericonr:
- fix configure args and hostmakedepends to actually enable gettext for
our build
- remove configure args that match their defaults (documented in
README.md)
- add _revision to VERSION_EXTRA for a bit more free debugging info, if
necessary
- fix minetest_game unpacking to not leave a folder in builddir after
the package's been built, not extract the archive twice and not
require tar in hostmakedepends (it never was actually required, it
could have been replaced by bsdtar)
Closes: #31000 [via git-merge-pr]
