tools build: Don't assume libtracefs-devel is always available

perf doesn't use libtracefs and so it doesn't make sense to assume it is
always available when building test-all.bin, defeating the feature check
speedup it provides.

The other tools/build/ users such as rtla, rv, etc call $(feature_check
libtracefs) to check its availability instead of using the test-all.bin
mechanism, stopping the build and asking for libtracefs-devel to be
installed.

Remove it from FEATURE_TESTS_BASIC to not have it as available, as noted
by Ian Rogers during review.
