Rework the function to use a single snprintf call instead of a mix of
strcpy/strcats. This now also appends a trailing slash where needed so we
don't rely on the build system to set this for us.
Also, since /tmp/ is the fallback and we never check if everything succeeded,
assert if we can't use /tmp/. This will never be triggered anyway, the only
caller to OutputDirectory() uses sizeof(PATH_MAX-sized array).

The X server uses this directory to store the compiled version of the
current keymap and/or any scratch keymaps used by clients. The X server
or some other tool might destroy or replace the files in this directory,
so it is not a safe place to store compiled keymaps for long periods of
time. The default keymap for any server is usually stored in:
X<num>-default.xkm
where <num> is the display number of the server in question, which makes
it possible for several servers *on the same host* to share the same
directory.
Unless the X server is modified, sharing this directory between servers on
different hosts could cause problems.
