[bug#35369] [PATCH] system: Change default kernel-arguments to '("quiet").

[Christopher Baines <mail@cbaines.net>]

This improves the readability of the boot process, especially when using full
disk encryption where you're required to enter the passphrase at a particular
point.

* gnu/system.scm (<operating-system>)[kernel-arguments]: Change the default to
'("quiet").
* doc/guix.texi (operating-system Reference): Document this change.
