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.

This change is motivated by attempts to run programs (like GNU IceCat) within
containers. The 'fontconfig' program, for example, is configured explicitly
to check ~/.guix-profile for additional fonts.
There were no existing container tests in 'tests/guix-environment.sh', but I
added one anyway for this change.
* doc/guix.texi (Invoking guix environment): Add '--link-profile'.

Partitions can have their own labels and UUIDs (e.g. under GPT) that are

system' for `partition' when talking about labels and UUIDs.
The text refers to a snippet which has since been removed, but a
