feat(extend_payload_to_esp):add payload to bootupd efi updates dir.

Bootup extend_payload_to_esp <path> will move the it to /usr

This features gives user ability to stage payloads to be picked up by
metadata generator.This will help in mounting fimwares and uboot binaries
to esp as required by rpi4.
example usage: `bootupctl backend extend_payload_to_esp /usr/lib/mydata`
will move the content of the dir to
`/usr/lib/efi/firmware/<name>/<version>/EFI/boot/efi/`
