All cros-debug versions of crosvm enabled seccomp logging, which is now
broken on kernels <4.4 thanks to new minijail changes as explained in
the referenced BUG. This seems to be intended by the minijail folks as
the aim to improve the seccomp logging in part by changing its semantics
to logging failures without killing the violating process. In such a
world, crosvm should not as a compile time choice, enable logging, which
would amount to disabling some of the security. This change adds a
command line flag to emulate the old behavior for the purposes of
developer debugging, as long as that developer is running on a kernel
that supports the new minijail seccomp filter failure logging.
