eol: handle LockUnavailable error (issue2569)

If the repository is not locked when clearing the dirstate, then
running test-eol.t in a loop fails sooner or later with:

  ERROR: /home/mg/src/mercurial-crew/tests/test-eol.t output changed
  --- /home/mg/src/mercurial-crew/tests/test-eol.t
  +++ /home/mg/src/mercurial-crew/tests/test-eol.t.err

     % hg status (eol activated)
     M win.txt
     % hg commit
  +  nothing changed
     % hg status
     $ testmixed CRLF

However, if we cannot lock the repository, then we can also not make a
commit and so we can simply ignore a LockUnavailable error.

Set vars:

  $ CONTRIBDIR=$TESTDIR/../contrib

Prepare repo-a:

  $ mkdir repo-a
  $ cd repo-a
  $ hg init

  $ echo this is file a > a
  $ hg add a
  $ hg commit -m first

  $ echo adding to file a >> a
  $ hg commit -m second

  $ echo adding more to file a >> a
  $ hg commit -m third

Dump all revlogs to file repo.dump:

  $ find .hg/store -name "*.i" | sort | xargs python $CONTRIBDIR/dumprevlog > ../repo.dump
  $ cd ..

Undumping into repo-b:

  $ mkdir repo-b
  $ cd repo-b
  $ hg init
  $ python $CONTRIBDIR/undumprevlog < ../repo.dump
  .hg/store/00changelog.i
  .hg/store/00manifest.i
