Subject: [PATCH net-next] net: selftests: clean up
 tools/testing/selftests/net/lib/py/utils.py

This patch improves the utils.py module by removing unused imports
(errno, random), simplifying the fd_read_timeout() function by
eliminating unnecessary else clause, and cleaning up code style in the
defer class constructor.

Additionally, it renames the parameter in rand_port() from 'type' to
'stype' to avoid shadowing the built-in Python name 'type', improving
code clarity and preventing potential issues.

These changes enhance code readability and maintainability without
affecting functionality.
