gssd: base the size of the fd array on the RLIMIT_NOFILE limit.
We have previously raised the size of the 'pollarray' once (32 -> 256)
and I have had another request to make it bigger.
Rather than changing the hard-coded value, make it depend on
RLIMIT_NOFILE. This is an upper limit on the size of the array
that can be passed to poll() anyway.
