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

     % 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.

  $ hg init
  $ echo This is file a1 > a
  $ echo This is file b1 > b
  $ hg add a b
  $ hg commit -m "commit #0"
  $ echo This is file b22 > b
  $ hg commit -m "comment #1"
  $ hg update 0
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ rm b
  $ hg commit -A -m "comment #2"

  $ mv a c

In theory, we shouldn't need the "-y" below, but it prevents this test
from hanging when "hg update" erroneously prompts the user for "keep
or delete".

Should abort:

  $ hg update -y 1
  abort: crosses branches (merge branches or use --clean to discard changes)
  [255]
  $ mv c a

Should succeed:

  $ hg update -y 1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
