Whenever we ship fixed libopenssl binaries in DD, the Freeradius daemon fails
at startup because it detects a mismatch of the build time and runtime OpenSSL
version.

Since our OpenSSL updates for DD are ABI compatible we do not need or even want
this superflous check. Removing it saves us the effort to rebuild Freeradius
after every OpenSSL version bump.
