Do not warn about compatible OpenSSL upgrades

When releasing OpenSSL patch-level maintenance updates,
we do not want to rebuild binaries using it.
And since they guarantee ABI stability, we do not have to.

Without this patch, warning messages were produced
that confused users:
https://bugzilla.opensuse.org/show_bug.cgi?id=1129411

Fixes bug 30190; bugfix on 0.2.4.2-alpha commit 7607ad2bec
