[PATCH v4 1/3] Smart-http tests: Improve coverage in test t5560

[Tarmigan Casebolt <tarmigan+git@xxxxxxxxx>]

Commit 34b6cb8bb ("http-backend: Protect GIT_PROJECT_ROOT from /../
requests") added the path_info helper function to test t5560 but did
not use it.  We should use it as it provides another level of error
checking.

The /etc/.../passwd case is one that is not special (and the test
fails for reasons other than being aliased), so we remove that test
case.

Also rename the function from 'path_info' to 'expect_aliased'.

One thing to note is that
	expect_aliased 0 /repo.git/HEAD
test still does not actually test any results back from http-backend,
but that's also how it was before as well.
