Merge bitcoin/bitcoin#26446: build: Drop unneeded linking of contrib/devtools/ scripts

29ef26ae25 build: Drop unneeded linking of `contrib/devtools/` scripts (Hennadii Stepanov)
77779c3717 script: Improve `test-{security,symbol}-check.py` robustness (Hennadii Stepanov)

Pull request description:

  The build system targets `make test-security-check`, `make -C src check-security` and `make -C src check-symbols` run `contrib/devtools/{test-,}{security,symbol}-check.py` scripts from the top source directory, i.e. `$(top_srcdir)` in the current Autotools-based build system.

  This renders needless of linking of those scripts into the build directory.

  Both build systems, the current Autotools-based and the future CMake-based, benefit from this simplification.
