do not build DOCS and cloud-amd64 (sonic-net#140)

speed up kernel compile.

- DO_DOCS=False do not skip generate document package on 4.19, use DEB_BUILD_PROFILES=nodoc instead.
- use arch_amd64_none_amd64 to build the amd64 kernel package, avoid generating cloud-amd64 package.

As a result, jenkins pipeline linux-kernel-buster-build-pr job sonic-net#31 takes 1h 6min, compare to sonic-net#30 takes 1h 24min.
