linux-initrd: Add virtio modules to '%base-initrd-modules'.

Browse source 
Fixes a regression in installation tests, whereby 'guix system init'
would report that virtio modules are missing for the target devices.
In practice virtio modules were always available since 'base-initrd' was
always called with #:virtio? #t.  This commit simply moves them to
'%base-initrd-modules' so that 'guix system' knows they're available.

Reported by Danny Milosavljevic <dannym@scratchpost.org> at
<https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30629#112>.

* gnu/system/linux-initrd.scm (default-initrd-modules): Add virtio
modules.
(base-initrd): Remove #:virtio? and 'virtio-modules'.
* gnu/system/vm.scm (expression->derivation-in-linux-vm)
(system-qemu-image, virtualized-operating-system): Remove uses of
 #:virtio?.
* doc/guix.texi (Initial RAM Disk): Update 'base-initrd' doc.

mounted by the initrd, possibly in addition to the root file system specified
on the kernel command line via @code{--root}. @var{mapped-devices} is a list of device
mappings to realize before @var{file-systems} are mounted.
When @var{virtio?} is true, load additional modules so that the
initrd can be used as a QEMU guest with para-virtualized I/O drivers.
@var{qemu-networking?} and @var{volatile-root?} behaves as in @code{raw-initrd}.
The initrd is automatically populated with all the kernel modules necessary

modules can be listed in @var{extra-modules}. They will be added to the initrd, and
for @var{file-systems} and for the given options. Additional kernel
modules can be listed in @var{linux-modules}. They will be added to the initrd, and
loaded at boot time in the order in which they appear.
