selftests: txtimestamp: allow individual txtimestamp tests.

The wrapper script txtimestamp.sh executes a pre-defined list of testcases
sequentially without configuration options available.

Add an option (-r/--run) to setup the test namespace and pass remaining
arguments to txtimestamp binary. The script still runs all tests when no
argument is passed.
