selftests/landlock: Test network denial context
Network denial events now report the port from their one authoritative
validated address through one signed field.  Verify this value directly
without inferring a source or destination role.

Exercise a nonzero IPv4 TCP bind, an explicit-zero IPv4 UDP bind, a
synthetic-zero IPv6 UDP autobind, and a family-only AF_UNSPEC UDP send.
Require exactly one event with the exact policy blocker for each shape.
The value -1 distinguishes a family-only address with no validated port
from the two valid port-zero cases.

Test coverage for security/landlock is 91.6% of 2625 lines according to
LLVM 22.
