Changes

While looking at seccomp and associated tests, I noticed they were a bit verbose. Refactored to make them simpler.

It makes it easier to configure pylint

Signed-off-by: Pablo Barbáchano <[email protected]>
I think this lint is not useful, and makes writing small classes more
difficult than it needs to be.

- convert inline JSON to dicts
- use pytest temporary files instead of tempfile
- create a seccompiler fixture to make running it easy

seccompiler --basic filters are deprecated

Add a test to validate that a seccomp filter works as defined in the
JSON description.

To do this we use a simple C program that just loads a given seccomp
filter and calls a syscall also given in the arguments.
