cos-dkms: Add option to infer kernel version from build id

When --kernel-version=cos-default is passed, the kernel version will be
inferred from the kernel headers for that build. This makes it easier to
1. use cos-dkms to build kernel modules for multiple COS builds, and
2. use cos-dkms to build kernel modules from a non-COS machine.

BUG=None
TEST=presubmit, on a cloudtop: `docker run -it -v $PWD:/usr/src/mymodule-1.0 cos-dkms:test build mymodule/1.0 --install-build-dependencies --make-variables=cos-default --build-id=19126.0.0 --kernel-version=cos-default`
