networkselftest: Fix handling of the smbclient process.

When the server could not be reached, the test previously,
produced:

FAIL!  : tst_NetworkSelfTest::smbServer() 'smbclient.waitForFinished(5000)' returned FALSE. ()
-   Loc: [tst_networkselftest.cpp(992)]
QWARN  : tst_NetworkSelfTest::smbServer() QProcess: Destroyed while process ("smbclient") is still running.

Fix this by:
- Using QStandardPaths::findExecutable to locate the binary instead
  of test-wise starting it.
- Add a function to ensure process termination.
- Pass a timeout argument to smbclient and pass an interval
  depending on it to waitForFinished(), which should prevent
  having to kill the process in most cases.
- Add proper error message
