[LLVM] Update maintainers for binary utilities

[nikic]

See developer policy for context on the maintainers terminology.

We currently list @jakehehrlich as the maintainer for llvm-objcopy / ObjCopy, but he hasn't been involved with LLVM for more than 5 years.

Looking through the contribution history it's not very obvious who to nominate as a replacement here, but I think @MaskRay is the main person with regular contributions in this area.

llvm-objcopy is a stable, largely mature drop-in replacement for GNU objcopy, including LLVM extensions.
It is so stable that it doesn't receive much active development.

I suggest that we replace the specific tool llvm-objcopy/ObjCopy with the broader "LLVM binary utilities".
(In addition, we have a llvm:binary-utilities new PR label, but not for llvm-objcopy.)

@jh7370 has been the most active reviewer in this area, so I'd like to nominate him as well.
(As we allow multiple maintainers, you may name both of us.)
While James might be less active in patch contribution, his provides invaluable code review, which is essential to catch potential issues and ensure code maintainability

Thanks, that makes a lot of sense.

Thanks for pointing that out, I've added @jh7370 now! Unfortunately GitHub only makes it easy to find people who often commit to an area, but not people who often review :(

Thanks!

I'm happy to accept this myself.

There are a handful of what some people will consider "binary utilities" that I don't contribute to (i.e. review), but I think this is a reasonable thing nonetheless.
