DIST_TUPLE: fix mv(1) for codeberg

Hi,

It looks like amongst the different code forges/sources for DIST_TUPLE,
codeberg is a special case in that it extracts just to ${_project}
instead of something like ${_project}-${_id}. The current ports that
use codeberg all only use it with '.' at the end of DIST_TUPLE, so
without a mv(1). While working on updating games/godot, godotsteam is
now hosted on codeberg, too. When pulling this in with

DIST_TUPLE += codeberg godotsteam godotsteam v3.20 godotsteam

the MODDIST-TUPLE_post-extract fails because DIST_TUPLE gets the
directory wrong by including the ${_id}.

The diff below fixes this . It doesn't address the WRKDIST at this
point for the other ports that already use DIST_TUPLE for codeberg and
that all set WRKDIST manually. Fixing that will be a bit more
involved...

I tested the change with dist-tuple.test [1] which confirms that none
of the DIST_TUPLE-derived variables in existing ports change in the
existing ports tree.

ok?
