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.
