The helper bpf_get_current_pid_tgid returns wrong PID for process in container

[Alan-Jowett]

Steps:

1. Run https://github.com/Alan-Jowett/connection_tracker/
2. Run curl 1.1.1.1 from within a Windows isolated container

Expected result:
Shows the PID of the process doing the curl.

Actual result:
PID shows up as 4 (aka system).

This appears to be a host OS issue. The processId field in FWPS_INCOMING_METADATA_VALUES0 appears to be incorrect.

Fixing this will probably require an OS change.
