cros_bundle_firmware: Select u-boot or u-boot.elf for x86

When using coreboot we need the elf file, not the binary. Select this
automatically for now.

Another solution might be to add a separate parameter for specifying a
U-Boot elf file, or perhaps explicitly requiring that the correct one
should be given. In the transition this method is convenient, though,
since we don't break any ebuilds.

Use 'cros_bundle_firmware -u' with a u-boot.bin and see that it correctly
picks up the u-boot elf file instead.
