Last call: Migration of Mk/bsd.apache.mk to Uses/apache.mk

[Bernard Spil]

Hi all,

This change is now past-due.

Please review https://reviews.freebsd.org/D12308 or check the version I 
have in my private repo on https://github.com/Sp1l/freebsd-ports
Please test this and tell me if there are regressions.

In 2 weeks I will be committing this to the ports tree unless there are 
comments I have to fix, preferably on the Phabricator review.

Thanks,

Bernard.
