debugd: Collect memory fragmentation info

Project Member Reported by vovoy@chromium.org, Feb 1 2018 
Recently, there are some sluggish issue on chromebox.
https://listnr.corp.google.com/product/208/report/84996226959

One potential cause is the system memory is fragmented.
To check memory fragmentation status, add buddyinfo to system_log.
