linuxci: test compiling linux

Similarly to Xen, CBMC should be able to compile the linux kernel. As
compiling the full kernel is very time consuming, and with CBMC also
space consuming, only compile a single file and all its dependencies,
with the smalles configuration possible.

Once this is working, the configuration, as well as targets to be
compiled can be increased.
