Subject: linux-initrd: Factorize 'check-device-initrd-modules'.

* gnu/system/mapped-devices.scm (check-device-initrd-modules): Move to...
* gnu/system/linux-initrd.scm (check-device-initrd-modules): ... here.
New procedure.
* po/guix/POTFILES.in: Add it.
* guix/scripts/system.scm (check-initrd-modules)[check-device]: Remove.
Use 'check-device-initrd-modules' instead.
