Fix: Tests: utils.sh: fix unbound variable

When loading `utils.sh`, we test the `LTTNG_TEST_TEARDOWN_TIMEOUT` and
define it to a default value if it's not defined already.

When running bash test scripts with the `-u` option to error out when
encountering unset variables it prints an error and exit
