[Release] Checkmk stable release 2.2.0p15

In the CRE deb package for Ubuntu 22.04 (and probably others), there is a bug with active checks that depend on openssl, e.g. check_http, check_ftp, check_tcp etc. These checks go critical after the update, saying

(Return code of 127 is out of bounds - plugin may be missing)

Workaround:

Symlink the old libraries like so (you might need to adapt the paths to your environment):

cd /opt/omd/versions/2.2.0p15.cre/lib
ln -s /opt/omd/versions/2.2.0p14.cre/lib/libcrypto.so.1.1
ln -s /opt/omd/versions/2.2.0p14.cre/lib/libssl.so.1.1

I have already notified feedback@checkmk.com about this.
