Add print-PLIST target for automatic PLIST generation:

- files & symlinks first
  - @exec/@unexec calls are added for info files
  - @dirrm statements last
  - empty directories are handled properly
  - dirs from mtree files are excluded

Usage:
  - make install
  - make print-PLIST | brain >pkg/PLIST

Moved over from bsd.hf-pkg.mk, after it's lived there for quite
some time now.
