    Makefile: fix dependencies for generated .h, .c
    
    We have a single rule generating .c and .h files,
    so .h doesn't depend on .c: both depend on the
    source schema.
    
    Fix Makefile to reflect that - without this,
    if .c is there and .h is missing, Makefile does
    not know how to remake .h and assumes it's
    a dummy target, triggering endless rebuilds.
