Dylan Reid d6c579fcef io_jail: Add a wrapper around minijail
The io_jail is used to jail io processes run from crosvm. Under the hood
it mostly configures a minijail jail to run in.  The minijail
restrictions are applied when iojail::enter is called.  This closes
extra FDs and calls minijail_enter.

The minijail_run* functions are left out as we don't have a need to exec
foreign programs.  libminijail will be used to jail separate processes
spawned from the main crosvm process.

The ability to close all open file descriptors is added.  Minijail only
closes FDs after forking and before exec.
