Don't treat TMUX_TMPDIR as a potential file
The point of setting TMUX_TMPDIR is to then make any labels from -L go
to that directory. In the case of makesocketpath() with no TMUX_TMPDIR
set, would set both the path and the default socket to a file. The
checking of the permissions on the file worked fine in that case, but
when TMUX_TMPDIR is set, won't work on a directory.
This fixes the problem by ensuring the check on the permissions is
performed on directories only.
