[PATCH 1/3] libtracefs: Fix trace options unit test

["Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>]

Changes to tracefs library APIs were introduced by this patch set:
https://lore.kernel.org/linux-trace-devel/20210409180423.72497-1-y.karadz@gmail.com/
which make the option mask immutable and controlled by the library.
However, the unit test was not updated and fails.
Fixed the trace options unit test, to reflect the changes in the API.
