[pyro][PATCH 14/17] kernel-uboot: support compressed kernel on MIPS

["André Draszik" <git@andred.net>]

From: André Draszik <adraszik@tycoint.com>

MIPS generates vmlinuz.bin when compression in the kernel build is
enabled, including any necessary objcopy so we can leverage that
and skip our manual invocation of objcopy here. We just have to
put the file into the right place for the rest of the build to
find it.
