Remove fcntlLong, use fcntlInt for F_SETFD instead.

fcntlLong works too, but only because of the syscall conventions
happen to place the lower 32 bits of our jlong in the right register.

This change also gets rid of fcntlLong because there aren't any
documented fcntl calls that take a 64 bit integer argument.
