gui-init: Implement blob jail feature
Blob jail provides device firmware blobs to the OS, so the OS does not
have to ship them.  The firmware is passed through the initrd to
/run/firmware, so it works with both installed and live OSes, and there
are no race conditions between firmware load and firmware availability.

The injection method in the initrd is specific to the style of init
script used by PureOS, since it must add a copy command to copy the
firmware from the initrd to /run.  If the init script is not of this
type, boot proceeds without device firmware.

This feature can be enabled or disabled from the config GUI.

Blob jail is enabled automatically if the Intel AX200 Wi-Fi module is
installed and the feature hasn't been explicitly configured.
