vendor.sh: avoid unnecessary directory copy

the previous commit changed an mv to a cp. what it hacked
was actually a relic of the vgarom download patch that i
did for t480, before mate got native video init working.

this patch is the better fix. i double checked to be sure,
and nothing was using the files at the copied location.
the _extracted directory under cache gets deleted later on,
so it's perfectly acceptable to keep.

the other alternative would have been to simply change
the path in the sch5545 function to appdir, instead of
the cache dir, but who really cares?

this patch removes bloat from lbmk.
