go-cross-canadian: fix binaries install and GOARCH

set GOARCH to HOST_GOARCH which is set from SDKMACHINE,
since GOARCH defaults to TARGET_GOARCH, which is set from MACHINE (wrong arch).

Also fix do_install to correctly install all binaries from
${GO_BUILD_BINDIR} by using 'find -type f' to avoid issues when the
directory contains subdirectories (e.g. "linux_arm").
