getcwd: work around mingw bug

mingw getcwd(buf, 0) fails with ERANGE, instead of the required
EINVAL.  Since we're already replacing getcwd on mingw, the
workaround is trivial.

* lib/getcwd-lgpl.c (rpl_getcwd): Guarantee correct error.
* doc/posix-functions/getcwd.texi (getcwd): Document it.
Reported by Matthias Bolte.
