ipv4,ipv6: retry ENOBUFS in TestPacketConnReadWriteUnicastUDP

This ports CL 402059 to the non-concurrent UDP and ICMP variants of
the test.

(It isn't obvious to me whether the ENOBUFS retry loop is strictly
needed for the ICMP variants, but I'm getting kind of tired of porting
this CL to different tests and would rather minimize the number of
times it has to be done again. 😩)

Fixes golang/go#53402.
