system: Align zram priority with swap-space spec to clarify.
Fixes <https://issues.guix.gnu.org/54783>. * gnu/services/linux.scm (zram-device-configuration) [priority]: Adapt to use #f or an integer from 0 to 32767. Add sanitizer to warn for the change and delay the field. (zram-device-configuration->udev-string): Adapt as above. * doc/guix.texi (Zram Device Service): Remove double copyright line. Change priority description to refer to the Swap Space one, and suggest not leaving the default #f on to properly use zram.
