fsusage, mountlist, getloadavg, getgroups: Remove support for Ultrix.

* m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Don't define
STAT_STATFS2_FS_DATA.
* lib/fsusage.c: Remove STAT_STATFS2_FS_DATA case.
* m4/ls-mntd-fs.m4 (gl_LIST_MOUNTED_FILE_SYSTEMS): Don't define
MOUNTED_GETMNT.
* lib/mountlist.c: Remove MOUNTED_GETMNT case.
* lib/getloadavg.c (decstation): Remove definition and case.
* m4/getgroups.m4 (AC_FUNC_GETGROUPS): Mention NeXTstep, not Ultrix.
* lib/getgroups.c: Likewise.
* doc/posix-functions/getgroups.texi: Likewise.
* lib/time.in.h: Update comments.
