Subject: [PATCH v4] rtla: Documentation: Fix -t, --trace

Move -t, --trace from common_options.rst to
common_osnoise_options.rst and
common_timerlat_options.rst

so that it will appear in the man pages

rtla-timerlat-hist.1
rtla-timerlat-top.1
rtla-osnoise-hist.1
rtla-osnoise-top.1

Remove the equals ('=') sign and add a space.
