tests: fetch.py: use real subversion repository

* github no longer provides support for subversion clients:
  https://docs.github.com/en/enterprise-server@3.11/get-started/working-with-subversion-on-github/support-for-subversion-clients
  it was shut down on 2024-01-08:
  https://github.blog/2023-01-20-sunsetting-subversion-support/

  and this test was now failing with:

======================================================================

svn: warning: W205011: Error handling externals definition for 'trunk/bitbake':
svn: warning: W170013: Unable to connect to a repository at URL 'https://github.com/PhilipHazel/pcre2.git'
svn: E205011: Failure occurred processing one or more externals definitions

  in the rare cases where subversion was still installed on the host
  running bitbake-selftest :).

  to avoid this use still alive repository from https://svn.apache.org/
  and pick something rather small and only the trunk subdirectory which
  is fast to fetch:
  svn co https://svn.apache.org/repos/asf/serf/trunk
  takes just 2 sec here

  adjust expected dir/file to use "protocols/fcgi_buckets.h" instead of
  "trunk/README"
