samypr100 e730ef19f1 Patch additional sysconfig values such as clang at install time (#9916) ...

## Summary

Minor follow up to https://github.com/astral-sh/uv/pull/9905 to patch
`clang` with `cc`.

Implements the replacements used in
[sysconfigpatcher](https://github.com/bluss/sysconfigpatcher/blob/main/src/sysconfigpatcher.py#L54),
namely

```python
DEFAULT_VARIABLE_UPDATES = {
    "CC": WordReplace("clang", "cc"),
    "CXX": WordReplace("clang++", "c++"),
    "BLDSHARED": WordReplace("clang", "cc"),
    "LDSHARED": WordReplace("clang", "cc"),
    "LDCXXSHARED": WordReplace("clang++", "c++"),
    "LINKCC": WordReplace("clang", "cc"),
    "AR": "ar",
}
```

## Test Plan

Added an additional test. Tested local python installs.
