mk/targets.mk: Add version fallback for tag-less repos

* mk/targets.mk (ORGVERSION, GITVERSION): Get version from lisp/org.el
header if it can't be retrieved from git-describe.

As of elpa.git's ee03829f90 (Finalize the new master branch,
2020-12-14), org-release and org-git-version are empty strings in
https://elpa.gnu.org/packages/org-*.tar files.  This is because the
new setup executes `make autoloads info' in an elpa.git worktree with
an Org branch checked out, but elpa.git of course doesn't have Org's
release tags.

Maintaining the org.el version header has been a point of contention
in the past [1], but the header has been there for a while now.  Use
it to avoid the above elpa.git issue.  In the case of the master
branch, the org-release value generated in a tag-less repo will have a
different version than the one from a regular repo because org.el's
version header has a "-dev" suffix, but that's still better than an
empty version.
