FreeBSD: Update usage of py-sysctl

Browse Source 
py-sysctl now includes the CTLTYPE_NODE type nodes in the list returned
by sysctl.filter() on FreeBSD head.  It also provides descriptions now.

Eliminate the subprocess call to get descriptions, and filter out the
nodes so we only deal with values.
