t/lib-bundle-uri: use local fake bundle URLs

A few of the bundle URI tests point config at a fake bundle; they care
only that the client has been configured with _some_ bundle, but it
doesn't have to actually contain objects.

For the file:// tests, we use "$BUNDLE_URI_REPO_URI/fake.bdl", a
non-existent file inside the actual remote repo. But for git:// and
http:// tests, we use "https://example.com/fake.bdl". This works OK in
practice, but it means we actually make a request to example.com (which
returns a placeholder HTML response). That can be annoying when running
the test suite on a spotty network (it doesn't produce a wrong result,
since we expect it to fail, but it may introduce delays).

We can reduce our dependency on the outside world by using a local URL.
It would work to just do "file://$PWD/fake.bdl" here, since the bundle
code does not care about the actual location. But in the long run I
suspect we may have more restrictions on which protocols can be passed
around as bundle URIs. So instead, let's stick with the file:// repo's
pattern and just point to a bogus name based on the remote repo's URL.

For http this makes perfect sense; we'll make a request to the local
http server and find that there's nothing there. For git:// it's a
little weird, as you wouldn't normally access a bundle file over git://
at all. But it's probably the most reasonable guess we can make for now,
and anybody who tightens protocol selection later will know better
what's the best path forward.
