[PATCH 24/24] t5601: basic bundle URI tests

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <derrickstolee@github.com>

This test demonstrates an end-to-end form of the bundle URI feature
given by an HTTP server advertising the 'features' capability with a
bundle URI that is a bundle file on that same HTTP server. We verify
that we unbundled a bundle, which could only have happened if we
successfully downloaded that file.

RFC-TODO: Create similar tests throughout the series that perform
similar tests, including examples with table of contents and partial
clones.
