Add utilities to help checking capabilities of the running procss. Make
perf link with libcap, if it is available. If no libcap-dev[el], assume
no capabilities.
Committer testing:
$ make O=/tmp/build/perf -C tools/perf install-bin
make: Entering directory '/home/acme/git/perf/tools/perf'
BUILD: Doing 'make -j8' parallel build
Auto-detecting system features:

<SNIP>
Makefile.config:833: No libcap found, disables capability support, please install libcap-devel/libcap-dev

$ grep libcap /tmp/build/perf/FEATURE-DUMP
