            Log:
            remove gdb-6.3-mapping-zero-inode-test.patch

Upstream commit:

  commit fcfd8a4f2392d3882c07c4e127bfcfb53ca78728
  Date:   Wed May 7 12:58:41 2025 +0100

      gdb: support zero inode in generate-core-file command

includes a test that covers the same functionality as the test in
patch gdb-6.3-mapping-zero-inode-test.patch, so there's no point
carrying the local test any more.  We'll pick up the upstream test the
next time Fedora rebases.
