After Roll zlib to pick up more 1.2.12 fixes, the test standalone_2/io/socket_sigpipe_test fails on dartk-ubsan-linux-release-x64 due to a ubsan violation in the rolled version of zlib.

this has been failing for a long time now it seems(going at least to c44fb72 zlib rev, pre https://dart-review.googlesource.com/c/sdk/+/183042 roll): the diagnostic was in the spawned process stderr, so was ignored by the test.
