pkg_add/pkg_delete: include PID in syslog messages

[Lawrence Teo]

This simple diff makes pkg_add and pkg_delete include their PID when
logging to syslog. This is useful when trying to determine whether
several packages were added (or removed) by the same pkg_add (or
pkg_delete) process.

Here is some sample output:

Mar  3 22:15:17 obsd-amd64 pkg_add[3530]: Added nano-2.2.6 
Mar  3 22:15:26 obsd-amd64 pkg_delete[21136]: Removed nano-2.2.6 
Mar  3 22:16:51 obsd-amd64 pkg_add[30666]: Added redland-1.0.8p1 
Mar  3 22:16:54 obsd-amd64 pkg_add[30666]: Added mozilla-dicts-en-GB-1.3 
Mar  3 22:16:56 obsd-amd64 pkg_add[30666]: Added hunspell-1.2.12 
Mar  3 22:23:22 obsd-amd64 pkg_add[30666]: Added libreoffice-3.4.5.2v0 
Mar  3 23:33:23 obsd-amd64 pkg_add[5948]: Added kdiff3-0.9.96p1 

Comments?

Thanks,
Lawrence
