Collect ramoops data into BMC dump
- Add ramoops file monitor and support to enable ramoops data
collection for kernel dump.
- Systemd will collect ramoops data and write it into
/var/lib/systemd/pstore when a system kernel oops/panics.
- Today, need to grab everything in that directory, put it in a dump
and then delete everything in that directory.
Tested:
- Simulate a kernel panic by creating similar data in the expected
location.
