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.
