DEPENDS_ARGS doesn't work with packages and even if it did
WITH_MODPERL2 / WITH_MODPERL is not handled correctly so the depency list for
upcomming www/rt38 is way off.
As such, we've split this port into MASTER (www/p5-Apache-DBI) and
SLAVES (www/p5-Apache-DBI-mp1) and (www/p5-Apache-DBI-mp2).
While here, cleanup the MASTER port a little
- spell out the RUN_DEPENDS
- remove USE_APACHE and let www/mod_perl* deal with it
- pull the plist into Makefile
