Pull request: test: make test-debug-process locale-independent

The test `test/parallel/test-debug-process.js` fails on non-English Windows systems due to a locale-dependent error message string.

The test asserts that a call to `process._debugProcess()` on a terminated process throws an error with the message `'The system cannot find the file specified.'`. While this holds true on an English Windows system, the test fails on systems with a different display language.

The underlying `WinapiErrnoException` function correctly retrieves the localized error message from the OS. For example, on a Korean system, the message is "지정된 파일을 찾을 수 없습니다.". This mismatch causes an `AssertionError`.

This behavior can be verified directly in PowerShell:

### On Windows with English (US) display language
```powershell
PS> (New-Object System.ComponentModel.Win32Exception 2).Message 
The system cannot find the file specified.
```
### On Windows with Korean display language
```powershell
PS> (New-Object System.ComponentModel.Win32Exception 2).Message 
지정된 파일을 찾을 수 없습니다.
```
To make the test robust and environment-agnostic, this commit changes the assertion to check the language-independent `error.errno` property, which is consistently `2` for this type of error, instead of the localized `error.message`.
