largefiles: use the share source as the primary local store (issue4471)
The benefit of retargeting the local store to the share source is that all
shares will always have access to the largefiles any one of them commit, even if
the user cache is deleted (which is documented to be OK to do). Further, any
push into the source (and now any shares), will likewise make the largefile(s)
visible to all related repositories.
In order to maintain compatibility with existing repos, where the largefiles
would be cached only in the local share, fallback to searching the local share
if it isn't found at the share source.
The unshare command should probably be taught to copy the source store into the
store for the repo being unshared to complete the loop.
This patch changes the test like this:

The issue writeup mentions pushing a largefile from a remote repo to the main
local repo, and the largefile is then not available in any shares. Since the
push doesn't cache the largefile in $USERCACHE, the trashed $USERCACHE in this
test is equivalent.
