fa910b47656d0e69cccb1f31804f2b11aa45d053 util: Properly handle -noincludeconf on command line (MarcoFalke)

Pull request description:

  Before:

  ```
  $ ./src/qt/bitcoin-qt -noincludeconf
  (memory violation, can be observed with valgrind or similar)
  ```

  After:

  ```
  $ ./src/qt/bitcoin-qt -noincludeconf
  (passes startup)
  ```

  Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=34884
