ci: fix Mockito self-attach warning via byte-buddy-agent javaagent

Add maven-dependency-plugin:properties execution to resolve
net.bytebuddy:byte-buddy-agent:jar path at build time, then
load it as -javaagent in the surefire argLine. Eliminates the
"Mockito is currently self-attaching" warning without version
pinning.
