[PATCH] procd: don't let the user choose to mount /tmp on zram

The /tmp directory is mounted as tmpfs. The tmpfs filesystem is backed by
anonymous memory, which means it can be swapped out at any time, if there is
memory pressure [1]. For this reason, a zram swap device is a much better
choice than mounting /tmp on zram, since it's able to compress all anonymous
memory, and not just the memory assigned to /tmp. We already have the zram-swap
package for this specific purpose, which means procd's tmp-on-zram is both
redundant and more limited.
For the time being, don't allow the user to select this feature. Follow-up
patches will remove procd tmp-on-zram support altogether.
