We notice that:
BpfMap.reset(dupFd_with_cloexec(BpfMap.getMap())
is equivalent to
BpfMap = BpfMap
due to the current implementation of the BpfMap assignment operator.
Except the latter also verifies BpfMap<K,V> template types match.

In the BPF code, per-UID network access (e.g., for doze mode,
standby, etc.) is stored in UidOwnerValue structures. Each of
these stores that UID's rules in a 32-bit bitmask of
UidOwnerMatchType values, so the code can support ~31 match
types.
However, which match types are enabled is stored in
configuration_map at index UID_RULES_CONFIGURATION_KEY, and
configuration_map only stores 8-bit values. So it's not
possible to define more than 7 match types.
Widen configuration_map to from 8 to 32 bits to match the width
of UidOwnerValue.rule. This doesn't impact memory because
configuration_map only has 2 entries.

Currently, even when VPN Lockdown mode is enabled, incoming packets are
not dropped if VPN is not connected.
This commit fixed this issue.
After this commit, If VPN Lockdown mode is enabled, incoming packets
are dropped regardless of the VPN connectivity.

netlink_listener_test tests the socket destroy listener, so it makes
sense to just merge it into the TrafficControllerTest.
