Gracefully handle PermissionError exceptions that crash fuzzer

Fuzzing inputs sometimes produce directory paths that are protected inside the fuzzer execution environment. This is not an issue in GitPython's code, so it should not crash the fuzzer. Fixes OSS-Fuzz Issue 69456: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=69870
