Zach Reizner 5d586b73a4 sys_util: use MADV_DONTDUMP for new mmaps 
The mmaps made through the sys_util API are usually for guest memory or
other large shared memory chunks that will pollute the file system with
huge dumps on crash. By using MADV_DONTDUMP, we save the file system
from storing these useless data segments when crosvm crashes.
