More robust setuid, setgid, etc detection

Browse source 
* configure.ac: Check for getuid, getgid, setuid, and setgid.
* libguile/posix.c (scm_getuid, scm_getgid, scm_setuid, scm_setgid):
  Only provide Scheme functions if the OS provides these facilities.
  (scm_geteuid, scm_getegid, scm_seteuid, scm_setegid): Provide if the
  host has getuid, getgid, etc, instead of being in a MinGW guard.
