scripts: include binaries in patch

This commit allows for binary content in patches created via 'make
update-patches'.

Binary patches are needed for BDFs required for al boards on the new
ipq40xx target. Before this commit, binaries were omitted from the
generated patch which resulted in the patch not able to apply.

Patches without binary content do not differ in case they are created
with the '--binary' flag.
