False positive against openssh*-7.4p1-22.0.1.el7_9_fips

[prabhakarp-dev]

Similar to closed issue #1237 for openssl on OL8, there are actually two versions of openssh for Oracle Linux 7; the latest versions are:

• vanilla: openssh*-7.4p1-22.0.1.el7_9
• FIPS-validated for special environments: openssh*-7.4p1-22.0.1.el7_9_fips

Logic is needed to differentiate these; only the ELSA advisories for the already-installed flavor should be checked. The FIPS version of openssh has "_fips" suffixed to the version string.
