I think GUIX_LOCPATH should be set automatically.  There are no ill
effects of having it set when the directory doesn’t exist AFAIK.  Also,
only Guix honours GUIX_LOCPATH (hence the name), so it shouldn’t screw
up the behaviour of other applications.

This is a problem on all systems where Guix is used as a package
manager.

What do others think?  If it’s okay and my rationalisations above are
not mistaken I’d like to accept this change.
