tests: fix ERRORs and false FAILs on some platforms

* tests/misc/ls-time.sh: Skip the test rather than ERROR
when `touch -m -d ...` fails (Hurd).
* tests/tail-2/follow-stdin.sh: Avoid false FAILs by ignoring
the variances in sterror output.
* tests/rm/rm-readdir-fail.sh: Likewise.  Also avoid ERRORs
on systems that don't define _D_EXACT_NAMELEN.
