Title: FreeBSD sysctl does not include the "hw.physicalcpu" OID

FreeBSD does not seem to support "hw.physicalcpu", so it seems reasonable to remove it from Parallel.physical_processor_count(). Attempting to access it just raises an error on FreeBSD 9.

# uname -mor
FreeBSD 9.1-RELEASE amd64
# sysctl -n hw.physicalcpu
sysctl: unknown oid 'hw.physicalcpu'
