MAINTAINERS: Update powerpc BPF JIT maintainers

Hari Bathini has been updating and maintaining the powerpc BPF JIT since
a while now. Christophe Leroy has been doing the same for 32-bit
powerpc. Add them as maintainers for the powerpc BPF JIT.

I am no longer actively looking into the powerpc BPF JIT. Change my role
to that of a reviewer so that I can help with the odd query.
