Subject: [PATCH v1] perf build: Remove NO_LIBCAP that controls nothing

Using libcap was removed in commit e25ebda78e23 ("perf cap: Tidy up
and improve capability testing"), however, some build documentation
and a use of the NO_LIBCAP=1 were lingering. Remove these left over
bits.

Fixes: e25ebda78e23 ("perf cap: Tidy up and improve capability testing")
