eina tmp get - support other tmp dir env vars and dont use xdg runtime

xdg runtime dir is NOT a tmp dir in the normal sense. it's not world
writable nor world readable. only for the user.  using
eina_environment_tmp_get() would imply that it is a regular tmp dir,
not a per-user private only runtime dir. that is something else
entirely.

@fix
