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.
  `dmesg > /var/lib/systemd/pstore/dmesg1.txt`
  `dmesg > /var/lib/systemd/pstore/dmesg2.txt`
  `dmesg > /var/lib/systemd/pstore/dmesg3.txt`
  `dmesg > /var/lib/systemd/pstore/dmesg4.txt`
