python3-pyruvate: disable 64 bit atomics for mips

Use the same approach as librsvg to disable 64-bit atomics on platforms
which have 32-bit pointers or are otherwise not supported.

https://github.com/crossbeam-rs/crossbeam/blob/master/no_atomic.rs

https://doc.rust-lang.org/std/sync/atomic/#portability
"PowerPC and MIPS platforms with 32-bit pointers do not have AtomicU64
or AtomicI64 types."
