Raise the minimum supported OpenSSL version to 1.1.1

Browse Source 
Commit a70e01d430 retired support for OpenSSL 1.0.2 in order to get
rid of the need for manual initialization of the library.  This left our
API usage compatible with 1.1.0 which was defined as the minimum required
version. Also mention that 3.4 is the minimum version required when using
LibreSSL.

An upcoming commit will introduce support for configuring TLSv1.3 cipher
suites which require an API call in OpenSSL 1.1.1 and onwards.  In order
to support this setting this commit will set v1.1.1 as the new minimum
required version.  The version-specific call for randomness init added
in commit c3333dbc0c is removed as it's no longer needed.
