Prevent CTS from hanging if no UDP packet was received

Previously, CTS tests could block forever on attempting to read a packet
from a UDP socket.

This patch modifies the receive methods of the NativeUdpSocket wrapper,
allowing it to gracefully fail if UDP packets are not received.
This patch also updates the IKE over UDP encap socket test to use the
NativeUdpSocket wrapper, preventing the tests from hanging in the same
fashion.

Bug: 70938121
Test: Ran updated tests on walleye + marlin
