Help with changing gitlab based download urls in ports

[Matthias Fechner]

Dear all,

gitlab seems to have deactivated a path FreeBSD is currently using to 
download packages hosted on gitlab.com.

This also causes gitlab-ce to be not fetchable anymore.
I already created a review to fix this here (sry, it also includes an 
upgrade of gitlab-ce, but without the upgrade, it would not be possible 
to testbuild this modification):
https://reviews.freebsd.org/D29628

But I need some help.

If I do not define a new WRKSRC in the port itself, it does not compile.
It seems that somewhere I forgot to modify the WRKSRC.

I do not know the bsd.*.mk files to fully understand the problem.

Any help is really appreciated.

Thanks!

Gruß
Matthias
