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.

This really should have been added along with the poll timeout support,
which changed the syscalls used in every jailed device.

crosvm spawns a lot of processes/threads, and having these all use the same
name as the original process can be confusing. So at least in the instances
where Rust threads are spawned (vs. minijail_fork()), use a thread::Builder
to allow setting the thread name.
BUG=none
TEST=start crosvm, check thread names with top

By using libc's openlog, we can ensure that the internal state of the
libc syslogger is consistent with the syslog module. Minijail will be
able to print to stderr and the syslog in the same way the logging
macros in crosvm do. The FD the syslog module uses is shared with libc
and via `syslog::get_fds`, jailed processes can inherit the needed FDs
to continue logging.
Now that `sys_log::init()` must be called in single threaded process,
this moves its tests to the list of the serially run ones in
build_test.py.

We will almost certainly require different seccomp policy files for
different architectures. Move all the existing secommp policy files
into a common directory grouped by architecture.
This will make it easier to install them via the ebuild later.
