perf unwind: Do not put libunwind-{x86,aarch64} in FEATURE_TESTS_BASIC

As it is not normally available on x86_64 not being tested on test-all.c
but being in FEATURE_TESTS_BASIC ends up implying that those features
are present, which leads to trying to link with those libraries and a
build failure now that test-all.c is finally again building
successfully:

  /usr/bin/ld: cannot find -lunwind-x86
  /usr/bin/ld: cannot find -lunwind-aarch64
  collect2: error: ld returned 1 exit status
  make[3]: *** [Makefile:199: /tmp/build/perf/plugin_jbd2.so] Error 1
  make[3]: *** Waiting for unfinished jobs....
  /usr/bin/ld: cannot find -lunwind-x86
  /usr/bin/ld: cannot find -lunwind-aarch64

So remove those features from there and explicitely test them.

And then move this patch to just before the last one that allows this to
be exposed, so that we keep the tree bisectable.

With all this in place we get, at this point:
