[PATCH 3/3] Add Makefile.uk with all the build logic needed

[Cezar Craciunoiu <cezar.craciunoiu@xxxxxxxxx>]

The makefile uses the build system of the library (meson + ninja)
first to generate the object files in such a way that they compile
successfully. Afterwards they are linked with the object files from
unikraft.
Test object files can be added by making 'TESTS' 'YES' in menuconfig.

The only problem of this approach is that meson checks the system
first for available functions, components, etc. Because of this,
it checks the host system, not the future guest OS.
