Some kernels are built with overlayfs as a builtin and not a module.
For these the check via lsmod currently fails.
This improvement now checks the kernel configuration for the
CONFIG_OVERLAY_FS entry. Depending on the OS and kernel version the
build configuration can be in multiple places.
* [vm build] force Linux to drop cache before calling kvm
KVM need to allocate 2G memory for this build. The system memory might
be occupied by cache at the moment and doesn't have 2G chunk to give
out. Forcing Kernel to drop cache to boost the chance of getting 2G
memory.

* [build]: put stretch debian packages under target/debs/stretch/
* in stretch build phase, all debian packages built in that stage are placed under target/debs/stretch directory.
* for python-based debian packages, since they are really the same for jessie and stretch, they are placed under target/python-debs directory.

This can be used when sonic-buildimage repo is a git submodule of other
repo.
e.g) if sonic-buildimage is a git submodule of "parent" repo and
sonic-buildimage is just under the top directory of "parent" repo, we
can build sonic-buildimage like below
$ cd parent/sonic-buildimage
$ DOCKER_BUILDER_MOUNT=`realpath ../`:`realpath ../` \
DOCKER_BUILDER_WORKDIR=`pwd` make all
