filemerge: use a single temp dir instead of temp files

This can help to remove the clutter from UIs that display just the filenames;
instead of seeing foo~local.C9ru9r.txt and foo~base.2DMV22.txt (in the /tmp
directory on most platforms), we create a single new directory and use that,
producing filenames like /tmp/hgmerge.C9ru9r/foo~local.txt.
