Explicit list of allowed paths in mtree checks

[Juan Manuel Palacios]

	Hi Markus!

	While tweaking some of the mtree stuff to put together the 1.5.2  
release, I realized you list explicitly the paths that are allowed in  
your mtree checks in base/src/port1.0/portdestroot.tcl:

set prefixPaths [list bin etc include lib libexec sbin share src var  
www Applications Developer Library]

	But we have a very similar list in the base/doc/prefix.mtree file,  
which is where I thought you were reading your whitelist from.  
Doesn't it make sense to abstract the list in portdestroot.tcl and  
read it from that one file? It would allow us to have a single check  
point we'd need to edit to make whatever appropriate modifications to  
the hierarchy.
