Jiping Ma 8bb380ed7a initramfs-ostree: Support the driver switch in install
This commit supports switch drivers in installer.  It will
load drivers based on multi-drivers-switch=versioni[cvl-2.54,
cvl-4.10, cvl-4.0.1], the drivers will be loaded by "insmod"
command before udevd is started, and that ensures the correct
drivers will be loaded.

Legacy drivers:
ls /lib/modules/$(uname -r)/extra/
i40e-cvl-2.54  iavf-cvl-2.54  ice-cvl-2.54
i40e-cvl-4.10  iavf-cvl-4.10  ice-cvl-4.10

Latest drivers:
/lib/modules/$(uname -r)/updates/
i40e-cvl-4.0.1  iavf-cvl-4.0.1  ice-cvl-4.0.1

Testing:
- An ISO image can be built successfully.
- Create prestage ISO and install this ISO image with qemu.
  Create prestage ISO including the multi-drivers-switch=cvl-2.54
  parameter.
- kernel dmesg show that the cvl-2.54 NIC drivers loaded during
  the install stage.
