compat: fix obslog compatiblity with 4.3
Due to the way of how successor sets are retrieved in new Mercurial version,
retrieving it again in 4.3 way would be a performance hit and complexify the
code too much.
Don't retrieve markers of successor sets which makes obslog filtered output
more limited in 4.3.
