Solaris buildpkg.sh: postinstall script added

[Darren Tucker]

Hello.
	I've added a postinstall script and a few mods to the Solaris
buildpkg.sh to:

* Save previous configs and create them from defaults if necessary
* (re)start sshd

This has been tested on Solaris 2.6 only.

The patch can be had from either of:
http://www.zip.com.au/~dtucker/openssh-3.0.2p1-buildpkg.patch
http://home.usf.advantra.com.au/~dtucker/openssh-3.0.2p1-buildpkg.patch
