docker,drbd: ensure build on all Ubuntu kernels

Ubuntu has multiple kernel versions that may use different GCC versions.
In order to install all GCC versions that are needed to build kernel modules,
we can use the "dkms" package. We don't want to install any unnecessary
dependencies, so we parse the dependencies and select all gcc packages.
