darwin: resolve rb symbols from ext by `-flat_namespace` to see libruby transitively
This repairs the assumption, which many fat-gem maintainer expect, "An
extension built with --disable-shared Ruby is loadable from
--enable-shared Ruby".
By default all references resolved to a dynamic library use "two-level
namespace", which record the library name and symbol name for each
resolution entry. On the other hand, `-flat_namespace` discards the
library name information and resolves symbols "flatly".
This behavior is useful for us to ignore which image (`ruby`
executable or `libruby.dylib`) provides rb symbols at runtime.
