Catch BrokenPipeError in SingleTLSLayerTestCase (#3547)

cjwatson · web-flow · commit a901452c4fda · 2025-02-03T00:36:37.000+02:00
OpenSSL 3.4.0 returns `ERR_LIB_SYS` in some more situations than it used to. In the case exercised by `SingleTLSLayerTestCase.test_close_after_handshake`, python/cpython#127361 (also backported to the 3.12 and 3.13 branches) turns this into `BrokenPipeError`. It seems reasonable to treat this in the same way as `ConnectionAbortedError` and `ConnectionResetError`.
