tools build feature: Move dwarf post unwind choice output into perf

We decide what dwarf unwind to choose way after the Makefile.feature
makefile is included. The $(dwarf-post-unwind) is not even set at that
time. For the same reason it was never included in FEATURE-DUMP file.

Moving it into perf VF=1 verbose display.

$ make VF=1
BUILD: Doing 'make -j4' parallel build
Auto-detecting system features:
... dwarf: [ on ]
...
... LIBUNWIND_DIR:
... LIBDW_DIR:
... DWARF post unwind library: libunwind
...
