makepkg: add the $startdir to package .BUILDINFO

This value is needed for reproducible builds. The reason is because
$BUILDDIR changes its behavior depending on whether it is the same as
$startdir, and the result is that we cannot know whether $srcdir (the
path that is potentially embedded into the final package) is actually
"$BUILDDIR/src" or "$BUILDDIR/$pkgbase/src".
