Add a custom Chrome OS rsyslogd configuration file.
Add a custom Chrome OS rsyslogd configuration file.

The file contents are copied from customize_rootfs with added copyright.

The file is currently unused -- it will be used instead of /etc/rsyslog.conf. A
separate CL will modify the ebuild (in the chromiumos-overlay repo) to install
it, and then a subsequent CL will modify syslog.conf to use it. This way things
won't break, hopefully.

BUG=chromium-os:11547
TEST=emerge-x86-mario chromeos-init -- worked fine, rsyslog.chromeos wasn't
installed
