    dumper: use cflags passed through --cflags-begin/end
    
    When GI is build without an installed glib and meson builds glib as
    a subproject the include paths are passed through --cflags-begin/end.
    The dumper didn't use them but worked anyway if glib was installed
    somewhere and pkg-config returned some cflags.
    
    This make the GI build work with meson without having glib installed.
