tools build: Don't show libbfd build status as it is opt-in

[ Upstream commit e0eb84cd51 ]

Since dd317df072 ("perf build: Make binutil libraries opt in")
doesn't try to build with binutils libraries, so showing that it is OFF
when building causes just distraction, remove it from FEATURES_DISPLAY.

For people that for some reason notice that there is always 'perf -vv',
a short hand for 'perf version --build-options' and 'perf check feature
libbfd' that now explains why it is not built:

  $ perf check feature libbfd
  libbfd: [ OFF ]  # HAVE_LIBBFD_SUPPORT ( tip: Deprecated, license incompatibility, use BUILD_NONDISTRO=1 and install binutils-dev[el] )
  $
