Collin Funk ec77664a31 tests: avoid failures if 'ulimit -n' cannot set file descriptor limits ...

This fixes test failures seen on Haiku.

* tests/ls/recursive.sh: Run 'ls' even if ulimit fails.
* tests/split/r-chunk.sh: Run 'split' even if ulimit fails.
* tests/sort/sort-merge-fdlimit.sh: Skip test if 'ulimit -n' cannot set
file descriptor limits.
