If a platform doesn't have posix_fadvise(), we don't allow
effective_io_concurrency to be set to anything but zero:
test=> set effective_io_concurrency = 1;
ERROR: 1 is outside the valid range for parameter
"effective_io_concurrency" (0 .. 0)
test=> set effective_io_concurrency = 0;
SET
Do we want to give a more informative error message, like "not supported
on this platform?"
