[Midnightbsd-cvs] src: mport.c: Fix a longstanding bug with the deleteall feature.

Log Message:
-----------
Fix a longstanding bug with the deleteall feature. Check for updepends before deleting a port.  We want to delete them from top down in case the deinstall scripts do anything and also so we don't get warnings about ports depending on downdepends.
