contrib/solaris/opensshd.in patch

[Rob Mallory]

This patch adds the seatbelts which  _only_ kill parent sshd procs... -RMallory
(eg: when you ssh into a machine and pkgadd the new openssh, it will not
     kill your current (or anyone else's sshd session)

onanother_note: the buildpkg.sh could use some exec_prefix functionality...
to deal with ./configure --prefix= --exec_prefix=/usr
