ci: Fix build of ubi8-based assembly

[RomanNikitenko]

What does this PR do?

npm install fails during Docker build on linux-libc-ubi8.Dockerfile with:

/bin/sh: /usr/lib/node_modules/npm/node_modules/node-gyp/gyp/gyp_main.py: /usr/bin/python3.8: bad interpreter: No such file or directory
make: *** [Makefile:343: Makefile] Error 126

Root cause: Red Hat's ubi8/nodejs-24 (and nodejs-22) images ship node-gyp's gyp_main.py with shebang #!/usr/bin/python3.8 (baked in by brp-mangle-shebangs during RPM build), but the actual Python in the image is 3.12 at /usr/bin/python3.

Fix: Add sed to rewrite the shebang to #!/usr/bin/python3 alongside the existing chmod +x in linux-libc-ubi8.Dockerfile

📝 Walkthrough

Walkthrough

The UBI8 builder no longer installs python3.9; its node-gyp entrypoints are made executable and updated to invoke /usr/bin/python3. The UBI9 builder also removes python3.9 and adds bash, tar, gzip, rsync, and patch to its installed dependencies.
