cc: Allow command line flag to prevent unit test timeouts.

When running layer tree tests in gdb, they easily time out
while stepping through code. This allows a command line flag
to override the timeout behaviour so that you can run the
tests in gdb without having to comment out the Timeout()
method.

The flag is --cc-layer-tree-test-no-timeout to make sure it's
not given by accident on the bots.
