Various MIPS cleanups

This PR contains a few cleanups to the MIPS part of the bindings. It mostly moves stuff out of `mips/mips32.rs` into `mips/mod.rs` which is identical between mips32 and mips64, mostly because mips64 is missing a number of syscalls. In addition, I add `struct flock` which was missing on mips64.
