[sle][security][sle15sp4][feature][manual] SLE-21539 - QA: bump stunnel to 5.59
New features according to website:
5.59 New features:
Client-side "protocol = ldap" support (thx to Bart Dopheide and Seth Grover). 5.58 New features: New 'protocolHeader' service-level option to insert custom 'connect' protocol negotiation headers. This feature can be used to impersonate other software (e.g. web browsers). 'protocolHost' can also be used to control the client SMTP protocol negotiation HELO/EHLO value. Initial FIPS 3.0 support.
stunnel is only required by uucp. So a version bump should not be very risky.
Current version in Leap 15.3/15.4 is 5.57
