tests: More SIGPIPE treatment as error

81f8d97b3486 ("tests: treat all signals as error") turned some SIGPIPE signals
to EPIPE, but missed tests/mini-dtls-mtu.c.

During

gnutls_bye(session, GNUTLS_SHUT_WR),

on Linux we get

client|<11>| WRITE: enqueued 39 bytes for 0x3. Total 39 bytes.
client|<11>| WRITE FLUSH: 39 bytes in buffer.
client|<2>| WRITE: -1 returned from 0x3, errno: 111
(ECONNREFUSED)

but on GNU/Hurd a SIGPIPE is sent instead of returning of ECONNREFUSED.
We thus need to turn it into an error to correctly interpret the test
result.
