hg: set default path correctly when doing a clone+share (issue5378)
Before, if performing a clone+share from a repo that was itself
using shared storage, the share code would copy paths.default from
the underlying repo being shared, not from the source given by
the user.
This patch teaches hg.clonewithshare to resolve paths.default
and pass it to share so it can be written to the hgrc accordingly.
