lang/go: Add bsd.go.mk and use it for go124 and go125

Previously, we used lang/go-devel as a MASTERDIR, but go-devel itself
was really old (essentially 3 years old), and Go doesn't have the
concept of a public "development" version anymore.

Rather than tying modern Go ports to a vestigial version that nobody
should actually use, this commit adds a bsd.go.mk that Go ports can
include. This allows us to get lang/go* Makefiles down to 3 lines.

While here, extend the pkg-descr for both lang/go and the lang/go1*
ports to help users understand what's installing what.

This "new" framework (gently modified from go-devel/Makefile, so all
credit goes to everyone involved in creating that file) provides for
a default pkg-descr, but keeps each port responsible for its own
patches.

No functional changes are intended other than a slightly extended
pkg-descr (not even important enough to bump PORTREVISIONs here). Any
change in behaviour is a bug.

lang/go-devel: move portscout to master port

Implements PORTSCOUT for all lang/go1* ports.

PR:	290231
Fixes:	c6297af4eff5e120d01d0c86c2d25d49418f389e "lang/go12[45]: silence
portscout"

lang/go12[45]: silence portscout

Because this does not make sense:

Port                                            | Current version | New version
------------------------------------------------+-----------------+------------
lang/go124                                      | 1.24.8          | 1.25.3
------------------------------------------------+-----------------+------------

And pet portclippy in the meantime by reordering some variables.

lang/go-devel: fix a4327166148114c314ae5dd6f9c7e6776178e0ac

There was a typo in the initial commit
Also the glob is on the file name not on the path, to use the hammer
and a wild glob, anyway golang has no external dependencies anyway
