Subject: [PATCH] fix GenericErrorWhenErrnoIsUnknown test on musl

testing on musl fails with error
```
sdbus-cpp/tests/unittests/Types_test.cpp:560: Failure
Value of: error.getMessage()
Expected: is equal to "custom message (Unknown error 123456)"
  Actual: "custom message (No error information)"
```
due to `musl` and `glibc` returning different error strings.

Extend test to cover both messages.

Closes: #544
