ssl: Remove use of crypto:rand_bytes/1
ssl already used crypto:strong_rand_bytes/1 for most operations as
its use cases are mostly cryptographical. Now crypto:strong_rand_bytes/1
will be used everywhere.
However crypto:rand_bytes/1 was used as fallback if
crypto:strong_rand_bytes/1 throws low_entropy, this
will no longer be the case. This is a potential incompatibility.
The fallback was introduced a long time ago for interoperability reasons.
Now days this should not be a problem, and if it is, the security
compromise is not acceptable anyway.
