golangci-lint: fix all the reported lint errors

[giuseppe]

commit 2d75d8e bumped the linter version without fixing the new issues.

Follow-up for #2482

Summary by Sourcery

Fix all reported lint errors by replacing context-less calls to exec.Command, net.Listen, and net.Dial with their context-aware counterparts across the codebase.

Enhancements:

• Use exec.CommandContext with context.Background() instead of exec.Command for all external command invocations
• Use net.ListenConfig.Listen with context.Background() instead of net.Listen for TCP listeners in tests
• Use net.Dialer.DialContext with context.Background() instead of net.Dial for UNIX socket connections

Reviewer's Guide

This PR migrates synchronous exec.Command, net.Listen, and net.Dial calls to their context-aware variants using context.Background, addressing lint errors introduced by the updated golangci-lint rules.
