Patch Analysis (matches upstream)

• Buddy Build 
• patch applied during the build (check rpm.log)
• patch include an upstream reference
• PR has security tag

[kgodara912]

Patch matches with upstream reference. Though the build logs do show one error,

/bin/sh: /usr/src/azl/BUILD/systemtap-5.0/missing: No such file or directory
make: *** [Makefile:823: Makefile.in] Error 127
touch: cannot touch '/var/lib/rpm-state/systemd-resolved.initial-installation': No such file or directory

which is unrelated to this PR, and we will fix that in separate PR. With that error also, the build is successful so that error is not fatal. Buddy build is successful. LGTM.
