Andre Klapper 6250296648 Correct call to non-existing PhutilFileLockException in support/unit/lock.php
Summary: `PhutilFileLockException` does not exist. Per https://we.phorge.it/source/arcanist/browse/master/src/filesystem/PhutilFileLock.php$54-66 , if lock acquisition fails it is supposed to throw a `PhutilLockException` instead.

Test Plan:
Grep the code base.

Or, run this, from arcanist, from two different terminals:

    php ./support/unit/lock.php asd.txt

After this change, the exception is correctly managed.
