update-pxe-network-installer: add updated firmwares

* Add a step to add updated firmwares from firmware rpms
  into the initrd

* The selected firmware file list will be provided through
  env variable UPDATE_FW_LIST.

* example usage:

echo "./usr/lib/firmware/fw1" > firmware-list
echo "./usr/lib/firmware/fw2" >> firmware-list
export UPDATE_FW_LIST="./firmware-list"
update-pxe-network-installer

Test Plan:

PASS: Add the firmware file location with the command:
echo "./usr/lib/firmware/qed/qed_init_values_zipped-8.42.2.0.bin" >> firmware-list
export UPDATE_FW_LIST="./firmware-list"
update-pxe-network-installer
