Avoid needless check on GNU/Linux.
* m4.include/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Omit STAT_STATFS3_OSF1 check
on GNU/Linux systems, since it can't possibly work.

fs usage: fix block size returned on older Linux 2.6.
* src/filemanager/mountlist.c: Fall back to (struct statfs).f_frsize
which is available since Linux 2.6.
* m4.include/fsusage.m4 (STAT_STATFS2_FRSIZE): Always define
when the member is available so it can be used as a fallback.

Sync with gnulib c25bdbae48977a527dff69150f59fb0746d31b51:
fs usage: check for GNU/Linux statvfs problem dynamically.
* src/filemanager/mountlist.c [STAT_STATVFS && __linux__ && (__GLIBC__||__UCLIBC__)]:
Define STAT_STATFS2_BSIZE too, since in this case the code now
checks dynamically whether statvfs is reliable, falling back on
Linux-style statfs otherwise.
(statvfs_works): New function, for dynamically testing statvfs.
(get_fs_usage) [STAT_STATVFS]: Use it.
* src/filemanager/filegui.c (filegui__check_attrs_on_fs): apply the same
statvfs_works function.
* m4.include/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Remove static check for
statvfs on GNU/Linux hosts, since it's now done dynamically.
