Could setup golangci-lint as a more effective linter in the future

The linter found a couple of instances where contexts were stored in structs; this is [against best practice](https://go.dev/blog/context-and-structs)

Done

I removed all the things

Hi, wanted to look at this recently and it seems to pass the tests, can this be closed?

This was with GMT (temporarily symlinked /etc/localtime to the appropriate file on Ubuntu 22.04)

It looks really broken :P

I've found the issue; at [dump_spec.rb#L37](https://github.com/david942j/seccomp-tools/blob/master/spec/cli/dump_spec.rb#L37) there is a test with a limit of 2, but the program only has one filter installed. This worked fine previously, but the change...

I fixed the test failures but am unsure how to stop it from printing the "no filter exists at this index" on test runs
