create $LIBUI_TMP_DIR on startup

$LIBUI_TMP_DIR might not exist.
Note that the mkdir could fail, in case the default libui-sh settings
(which use /tmp) don't work on the target system, in that case, it's up
to the user to init with a different directory spec, and if he will see
issues sooner or later.
