test: update test-sparse-revlog.t output

This test is skipped unless a large artefact is pre-build. It seems like nobody
ran it in a while. Changeset 3764330f76a6 changed the expected output but
nobody noticed.

This changeset focus on the first and simpler step: putting the expected output
back to what one would get by running this test.

However this test changes highlight a couple of deeper issues:

1) Even if the revision content did not changed, a change in the delta
contained in the bundle affected the delta stored in the final revlog, changing
the test result. Since we are testing the delta computation strategy with
sparse, we should not blindly reuse the delta-base from the bundled delta.

2) A change in the format of the repository used to generate the bundle changed
the delta stored in the bundle. We should get a more stable output to avoid
future instabilities of this test.

3) The test is it not run by CI or developer.

We'll try to address all this issues in the coming changesets.

#require reporevlogstore

A repo with unknown revlogv2 requirement string cannot be opened

  $ hg init invalidreq
  $ cd invalidreq
  $ echo exp-revlogv2.unknown >> .hg/requires
  $ hg log
  abort: repository requires features unknown to this Mercurial: exp-revlogv2.unknown!
  (see https://mercurial-scm.org/wiki/MissingRequirement for more information)
  [255]
  $ cd ..

Can create and open repo with revlog v2 requirement

  $ cat >> $HGRCPATH << EOF
  > [experimental]
  > revlogv2 = enable-unstable-format-and-corrupt-my-data
  > EOF

  $ hg init empty-repo
  $ cd empty-repo
  $ cat .hg/requires
  dotencode
  exp-revlogv2.1
  fncache
  sparserevlog
  store

  $ hg log

Unknown flags to revlog are rejected

  >>> with open('.hg/store/00changelog.i', 'wb') as fh:
  ...     fh.write(b'\x00\x04\xde\xad') and None

  $ hg log
  abort: unknown flags (0x04) in version 57005 revlog 00changelog.i!

  $ cd ..

Writing a simple revlog v2 works

  $ hg init simple
  $ cd simple
  $ touch foo
  $ hg -q commit -A -m initial

  $ hg log
