Neither existed under the guest root, so opening them failed and titles
that then read from the descriptor crashed. Opening either for reading
now returns a descriptor whose reads, positioned reads and vector reads
fill the buffer from the host's random device, as
sceRandomGetRandomNumber does. Opening them for writing throws.

Gathering every iovec into one host buffer threw for a total above
INT_MAX, which a console readv/writev accepts, and copied the whole
transfer twice. Each iovec is now read or written in place, in chunks
of at most INT_MAX bytes. A readv on a pipe returns after one read so
it does not block once the available bytes are consumed.
