transport-helper: add no-private-update capability

Since 664059fb (transport-helper: update remote helper namespace,
2013-04-17), a 'push' operation on a remote helper updates the
private ref by default. This is often a good thing, but it can also
be desirable to disable this update to force the next 'pull' to
re-import the pushed revisions.

Allow remote-helpers to disable the automatic update by introducing a new
capability.

When choosing between 'push' and 'export', Git prefers 'push'.
Other frontends may have some other order of preference.
'no-private-update'::
When using the 'refspec' capability, git normally updates the
private ref on successful push. This update is disabled when
the remote-helper declares the capability 'no-private-update'.
