MethodBind: Silence GCC `-Wmaybe-uninitialized` caused by UBSAN 

A priori this doesn't appear to be an actual bug, but a known consequence of
using UBSAN. We silence this one to still have the possibility to get more
warnings raised by UBSAN, in case they are useful.

Works around and closes #66343.
