Revert "UBUNTU: SAUCE: perf/bench: Drop definition of BIT in numa.c"

This reverts commit 54cba3ec.

Commit "UBUNTU: SAUCE: perf/bench: Drop definition of BIT in numa.c" is
causing build failures on tools/perf/bench after stable upstream commit
"perf tools: No need to include bitops.h in util.h" removed the
inclusion of the header file where the BIT() macro is defined. This
causes perf build failures when libnuma is installed.
