configure: Fix .tarball-version access from separate build tree

Browse source 
configure reads .tarball-version when the source tree isn't
git-controlled.  Fails when the build tree is separate.  Fix it to
read $srcdir/.tarball-version.

The occurence in Make.mk isn't wrong, because VPATH applies there.
Change it anyway, for consistency and a bit of extra robustness.
