Prevent spurious recompiles on account of changed version.
After a local commit, any file that included version.h would have to be recompiled on account of the changed version string. This changes version.h in the build directory to rbversion.h and includes the preprocessor macro from rbversion.h in firmware/common/version.c so that only that one file needs to be recompiled after a local commit rather than a whole slew of them.
