make-rules: use 'pkgdepend resolve -e' and REQUIRED_PACKAGES
The pkg(5) in OI is new enough now to allow the use of 'pkgdepend 
resolve -e' to vastly reduce build times at the expense of manually 
maintaining a list of dependencies.
This change allows that to happen in the "new" way, using the 
REQUIRED_PACKAGES list that most Makefiles already contain, rather than 
the "old" way way, using a static resolve.deps which was never actively 
used in OI.
