random: convert to using fops->read_iter()

This is a pre-requisite to wiring up splice() again for the random
and urandom drivers. It also allows us to remove the INT_MAX check in
getrandom(), because import_single_range() applies capping internally.

[Jason: rewrote get_random_bytes_user() to simplify and also incorporate
 additional suggestions from Al.]
