package/udev: move render and sgx to package/systemd

Moved groups render and sgx from UDEV_USERS to SYSTEMD_USERS as they
currently only appear in systemd's udev rules.

In systemd, group render was introduced since commit 4e15a73, and group
sgx was introduced since commit c9c4899.

In eudev, group render was introduced since commit bb070c1, but was
removed since commit a8ffcd1 [1].
