maint: omit unnecessary Gnulib modules

* basicdefs.h: Do not include alloca.h.
* bootstrap.conf (gnulib_modules): Remove alloca, stdalign,
c-ctype, closeout, mbrlen, verify.
Add version-etc.
* lib/.gitignore, m4/.gitignore: Omit now-unused files.
* po/POTFILES.in: Remove closeout.c.
* testsuite/test-mbrtowc.c: Do not include closeout.h.
(main): Close stdout by hand, to avoid a dependency on closeout.
