[LTP] [PATCH v3 3/4] tst_test.sh: Fix _tst_cleanup_timer() on set -e

[Petr Vorel]

If test exits on time (i.e. no timeout) kill in _tst_cleanup_timer()
have nothing to kill therefore following wait exits 143.

set -e (or #!/bin/sh -e or set -o errexit) quits on any non-zero exit code,
harden _tst_cleanup_timer() to be able to be used on scripts with it.
