changegroup: fix pulling to treemanifest repo from flat repo (issue5066)

In c0f11347b107 (changegroup: don't support versions 01 and 02 with
treemanifests, 2016-01-19), I stopped supporting use of cg1 and cg2
with treemanifest repos. What I had not considered was that it's
perfectly safe to pull *to* a treemanifest repo using any changegroup
version. As reported in issue5066, I therefore broke pull from old
repos into a treemanifest repo. It was not covered by the test case,
because that pulled from a local repo while enabling treemanifests,
which enabled treemanifests on the source repo as well. After
switching to pulling via HTTP, it breaks.

Fix by splitting up changegroup.supportedversions() into
supportedincomingversions() and supportedoutgoingversions().
