Proposed commit message

crowdstrike: parse command line to populate process name in FDR logs

This handles a special case occurs in Linux-based containerized environments
when the "runc" process clones itself to get into its own namespace.
The child process would have its executable path set to "/"
which was resulting in "process.name" being empty.

This change adds command line parsing to extract "process.name"
when "process.executable" is set to a slash ("/").

Adds fields definition for ChangeTime, OciContainerId and RootPath.
