[PATCH libevl v2 4/4] tests: Add latmus wrapper script for evl-test integration

Introduce a shell script wrapper that allows to invoke latmus as a
test binary like any other test:

The wrapper defaults to a 10-second timeout and no stdout if called
without arguments. If called with arguments latmus behaves like
directly called.

  evl test latmus            # runs with -T 10
  evl test latmus -- -A 150  # passes custom latmus arguments

This also allows to run latmus with the --stress-cmd option provided
by evl test:

  evl test --stress-cmd "stress-ng --cpu 1" latmus -- -T 60 -A 150
