seccomp2: Add "shutdown" to the list of permitted system calls.
We don't use this syscall, but openssl apparently does.
(This syscall puts a socket into a half-closed state. Don't worry:
It doesn't shut down the system or anything.)
Fixes bug 28183; bugfix on 0.2.5.1-alpha where the sandbox was
introduced.
