Omitting these packages would break backport libraries (such as dataclasses). Performance impact is negligible since the dependency graph has already been gathered.
Benchmarks using `$ hyperfine --warmup=1 --runs=10 './pants --no-remote-cache-{read,write} --no-pantsd dependencies ::'`
Before these changes (omitting stdlib dependencies):
```bash
Benchmark pantsbuild#1: ./pants --no-remote-cache-{read,write} --no-pantsd dependencies ::
Time (mean ± σ): 8.852 s ± 0.105 s [User: 8.612 s, System: 5.314 s]
Range (min … max): 8.702 s … 9.107 s 10 runs
```
After changes (with stdlib dependency inference)
```bash
Benchmark pantsbuild#1: ./pants --no-remote-cache-{read,write} --no-pantsd dependencies ::
Time (mean ± σ): 8.854 s ± 0.123 s [User: 8.619 s, System: 5.333 s]
Range (min … max): 8.682 s … 9.111 s 10 runs

Thanks so much @williamscs! FYI I merged with the title "Fix backports of std lib modules like I'll cherry-pick to 2.7 now |
