Add accessors for the build-time version of openssl.

Many bugs originate due to mismatches between the build-time and
run-time versions of openssl but they're hard to debug as we don't
provide access to the build-time info. This addresses that weakness.

[ChangeLog][QtNetwork][QSslSocket] Added accessors for the version
of openssl used at build-time. This will help when debugging
problems caused by a mismatch with the run-time version.
