FiiO M3K: New bootloaderbootloader_fiiom3k_v1

SPL and UCL-compressed bootloader are now packed into one output,
bootloader.m3k, eliminating the separate SPL build phase.

The Rockbox bootloader now has a recovery menu, accessible by
holding VOL+ when booting, that lets you back up, restore, and
update the bootloader from the device.
