Log Message:
Fix a couple of issues:

 - pkgin changed its output delimiter from a space to ';' when outputting
   to a non-tty, breaking various configuration management systems which
   relied on the previous behaviour.  Handle both types in ansible until
   NetBSDfr/pkgin#46 is resolved.

 - OS X 10.10 changed the behaviour of sysctl(8) to hide certain entries
   unless they are explicitly named.  Apply patch to fix hw.model and
   hw.usermem from https://github.com/ansible/ansible/pull/8171/files

Clean up patches while here.  Bump PKGREVISION.
