linux-initrd: Adjust VM code and doc to new 'base-initrd' signature.
This fixes regressions introduced in de1c158 ("system: Add support for
boot-time mapped devices.").
* doc/guix.texi (Initial RAM Disk): Adjust example with custom use of
'base-initrd'. Document #:mapped-devices parameter of 'base-initrd'.
* gnu/system/vm.scm (system-disk-image, system-qemu-image,
virtualized-operating-system): Adjust call to 'base-initrd' to new
signature.
