`recovery` does not work with pieeprom.bin

Describe the bug

When using the recovery folder to try and change the EEPROM on a Pi 4 (not CM4), it fails.

Steps to reproduce the behaviour

Connect a Pi4 configured to use rpiboot to your computer.

Attempt to run rpiboot -d . in the recovery folder. Notice how nothing happens.

As a work around, I renamed pieeprom.bin to pieeprom.upd, and upon running the same command again, the Pi applied the EEPROM update and rebooted.
