checkheads: clarify that we no longer touch the head unknown locally

Since c6cb21ddf74a, heads unknown locally no longer get any post processing
from obsolescence markers. We clarify this fact by only feeding the list of
locally known new heads to the function. This simplification of the input will
help moving that post-processing earlier in the function.

============================================
Testing obsolescence markers push: Cases A.6
============================================

Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).

This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.

Category A: simple cases
TestCase 6: new markers between changesets already known on both side
Variants:
# a: explicit push
# b: bare push

A.6  new markers between changesets already known on both side
==============================================================

Setup
-----

  $ . $TESTDIR/testlib/exchange-obsmarker-util.sh

initial

  $ setuprepos A.6
  creating test repo for test case A.6
  - pulldest
  - main
  - pushdest
  cd into `main` and proceed with env setup
  $ cd main
  $ mkcommit A0
  $ hg update -q 0
  $ mkcommit A1
  created new head

make both changeset known in remote

  $ hg push -qf ../pushdest
  $ hg push -qf ../pulldest

create a marker after this

  $ hg debugobsolete `getid 'desc(A0)'` `getid 'desc(A1)'`
  $ hg log -G --hidden
