[PATCH 3/3] bundle-uri: remove GIT_TEST_BUNDLE_URI env variable

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

From: Derrick Stolee <derrickstolee@github.com>

The GIT_TEST_BUNDLE_URI environment variable is used in the t573* suite
of tests that consume the bundle URIs advertised by the Git server. This
variable is equivalent to setting transfer.bundleURI=true, so we can do
that in these tests instead.

The environment variable has a name that implies it would be useful
outside of these tests. It is not useful to set across all tests since
it would do very little without some setup on the server side. Remove
it.
