Fix volumes and networks list/prune filters in http api

This is the continuation work started in #9711. It turns out
that list/prune commands for volumes in libpod/compat api have
very dangerous error handling when broken filter input is supplied.
Problem also affects network list/prune in libpod. This commit
unifies filter handling across libpod/compat api and adds sanity
apiv2 testcases.
