uwsgi: Remove post-fork hooks

[GSVarsha]

Autotrace webhook:

Python <= 3.11:

2025-11-20 05:04:24,241: 1 DEBUG instana: uwsgi hooks: decorators not available: likely not running under uWSGI

Reason:
uwsgi module not available for import hence, hitting the line here

Warning

uwsgi hooks not used/applied

Python >= 3.12:

2025-11-20 04:54:51,053: 1 DEBUG instana: uwsgi hooks: Running under uWSGI but decorators not available

Reason:
uwsgi has no attribute "opt" (Check out the card under Issue Links for the exact error message) hence, hitting the line here

Warning

uwsgi hooks still not used/applied

Inference:

Since in either case the uwsgi hooks are not really used and the fact that the automatic fork detection mechanism is robust enough to handle uwsgi worker forks without explicit hooks, we can safely remove the uwsgi hooks.
