cr-check: add ability to check if pidfd_store feature is supported
pidfd_store which will be used for reliable pidfd based pid reuse
detection for RPC clients requires two recent syscalls (pidfd_open
and pidfd_getfd).
We allow checking if pidfd_store is supported using:
1. CLI: criu check --feature pidfd_store
2. RPC: CRIU_REQ_TYPE__FEATURE_CHECK and set pidfd_store to
true in the "features" field of the request
