euidaccess: speed up 'configure' on GNU hosts

* m4/euidaccess.m4 (gl_FUNC_NONREENTRANT_EUIDACCESS):
Check for setregid here, not in gl_PREREQ_EUIDACCESS, since
it's needed only in this case.  Use AC_CHECK_DECLS, not
AC_CHECK_DECLS_ONCE.
(gl_PREREQ_EUIDACCESS): Do not use AC_CHECK_HEADERS_ONCE libgen.h
or AC_REQUIRE for AC_FUNC_GETGROUPS.
