GNU/Hurd doesn't support SO_PROTOCOL

Just noting that the test failure fixed by this is a 5.32 regression on Hurd.

@sthibaul did you test this? The build log at https://buildd.debian.org/status/fetch.php?pkg=perl&arch=hurd-i386&ver=5.32.0%7Erc1-1&stamp=1592442236&raw=0 has two failures, so I assume the system list on line 108 needs updating too.

Ah, no I hadn't tested it, because the issue was so obvious, and pointed to me by https://lists.debian.org/debian-hurd/2020/06/msg00028.html

Looks fine to me, though I don't know if 'gnu' is the precise correct string; but if it weren't @jmdh would have said something

[sthibaul]

'gnu' can be seen already used in various places:

dist/Time-HiRes/t/itimer.t:            && $^O ne 'gnu' # GNU/Hurd: has the API but no implementation
ext/POSIX/t/sigaction.t:            ($^O eq 'gnu')
t/io/socket.t:		    if $^O eq "gnu";

[jmdh]

Yep, I think "gnu" is correct.
