gh-109653: Reduce import overhead of uuid module on Linux (#115160)
This follows in the footsteps of #21586
This speeds up import uuid by about 6ms on Linux.
Before:
```
λ hyperfine -w 4 "./python -c 'import uuid'"
Benchmark 1: ./python -c 'import uuid'
Time (mean ± σ): 20.4 ms ± 0.4 ms [User: 16.7 ms, System: 3.8 ms]
Range (min … max): 19.6 ms … 21.8 ms 136 runs
```
After:
```
λ hyperfine -w 4 "./python -c 'import uuid'"
Benchmark 1: ./python -c 'import uuid'
Time (mean ± σ): 14.5 ms ± 0.3 ms [User: 11.5 ms, System: 3.2 ms]
Range (min … max): 13.9 ms … 16.0 ms 175 runs
```
