Subject: [PATCH 1/2] Fix path search upon `python3 -m  maturin`

`sysconfig.get_path` was insufficient on my machine as it was unable to resolve my `scripts` directory without an explicit `scheme="nt_user"` invocation (Windows 11 running Python 3.10.6). Intention here was to implement a more generic method of resolving `scripts` directories. There may be more idiomatic ways to achieve this behavior, as well as more useful error messages than what are provided in this solution.

In my haste to submit a pull-request I neglected to check format. Apologies.
