build: Disable GCC 8 -Wcast-function-type warning

GCC 8 introduces a -Wcast-function-type warning, that warns about type casts
that changes functions signatures. The C standard says that function pointer
of any type may be converted to a pointer to a function of another type and
back again, but calling the converted pointer is an undefined behaviour.

The problem is that GLib relies on this undefined behaviour and type casting
between different functions signatures is quite common. For example, this is
a compile error that happens because the command_source_on_input_ready which
is a function of type GPollableSourceFunc, is casted to GSourceFunc:
