UploadPackTest: Move "reachability" tests to its own file 

UploadPackTest is already too long and it is covering too many aspects
of UploadPack. This makes difficult to see what is tests and if all
cases are covered.

Move the reachability-related tests to its own file. This moves also an
auxiliary function, reducing the length of UploadPack. Complete also the
coverage, adding combinations of bitmap availability/commits or
blobs/reachable or not.
