Renamed port and changed dep to rails50 as gitlab-ce 11.6 depends now on
rails50.

Bump PORTREVISION for ports depending on the canonical version of GCC
defined via Mk/bsd.default-versions.mk which has moved from GCC 7.4 t
GCC 8.2 under most circumstances.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, as a double check, everything INDEX-11 showed depending on lang/gcc7.

GitLab and related ports maintained by me: pass maintainership to Matthias
Fechner

Matthias has proven himself as capable and enthusiastic enough to update
www/gitlab on its own - which frees much of my time. :)

I wrote an update guide for him and everybody interested in it:
