tools build: Test for presence of libtraceevent and libtracefs in test-all.c

Since these are so far considered part of the basic set of libraries to
be present when building perf, have then in
tools/build/features/test-all.c.

They were already in the FEATURE_TESTS_BASIC variable of
tools/build/Makefile.feature, meaning if test-all.c builds, those
features would be set as present, but then we were calling "again"
(well, they were not in test-all.c, so were not really being tested) for
it to be detected, fix this all up by not calling feature_check for
those features but instead have them in test-all.c to be tested together
with the the set of basic expected libraries.
