ports/67151: Mk/bsd.port.mk - Add a way to handle PLIST_SUB like substitutions to a given file list.

[Florent Thoumie]

This is a new version of the patch.

o Useless ${CAT} has been removed (thanks to eik's notice)
o Now when using PORTDOCS comment style, each line beginning with
"@comment " is deleted from the output.
