* process.c (obj2gid): use getgrnum_r() only if getgrnam_r() and
  _SC_GETGR_R_SIZE_MAX is available.
  MirOS BSD (MirBSD 10 GENERIC#1382 i386) have getgrnam_r() but
  no _SC_GETGR_R_SIZE_MAX.
  (obj2uid): use getpwnam_r() only if getpwnam_r() and
  _SC_GETPW_R_SIZE_MAX is available.
  This is consistency for obj2gid.
  MirOS BSD have neither getpwnam_r() nor _SC_GETPW_R_SIZE_MAX.
