lib/securerandom.rb: test one byte to determine urandom or openssl
`SecureRandom#gen_random` determines whether urandom is available or not
by trying `Random.urandom(n)`. But, when n = 0, `Random.urandom(0)`
always succeeds even if urandom is not available, which leads to a wrong
decision.
When failed, `Random.urandom` returns nil instead of returning a shorter
string than required. So the check for `ret.length != n` is not needed.
