vppinfra: Put clib_perf* behind Linux checks and provide stubs for FreeBSD
As a placeholder stub out clib_perf functions on FreeBSD, the interface for performance counters on FreeBSD is different and will require its own implementation. Type: improvement Change-Id: I61511ebe5ee1fd6fe93d3179c7843c811f47a846 Signed-off-by: Tom Jones <thj@freebsd.org>
