dockerd: Build failure on mips64_octeonplus

Maintainer: @G-M0N3Y-2503
Environment: mips64_octeonplus, snapshot

Description:
Buildbots are getting an error when building dockerd for mips64_octeonplus, from the faillog:

---> Making bundle: binary (in bundles/binary)
Building static bundles/binary-daemon/dockerd (linux/mips64)...

time: package/feeds/packages/dockerd/compile#208.06#49.39#224.30

The makefile excludes mips/mipsel but not mips64/mips64el - should the makefile be updated to exclude mips64 or should can this build error be fixed?

Start with the dockerd Makefile exclusion at the linked line and the mips64 compile errors in vendor/github.com/moby/buildkit/snapshot/diffapply_unix.go, using the linked faillog as the failure reference. Determine whether the package should exclude mips64 or whether the build error can be fixed, then verify the chosen resolution with a successful mips64_octeonplus build.
