    libs/guest: rework CFLAGS
    
    Remove '-Werror -Wmissing-progress -I./include $(CFLAGS_xeninclude)',
    those flags are already added via "libs.mk".
    
    Flag "-I." isn't needed, we just need to fix the #include of
    "xg_core.h" as this header isn't expected to be installed.
    
    Make use of "-iquote" instead of '-I' for double-quote included
    headers.
    
    Also, regroup the CFLAGS into the same place in the makefile.
