Catch exception when logging to systemd journal fails

systemd journal will throw IOError exception when journal.sendv() fails.
This catches that and falls back to syslog.  See issue #2773.
Implement python-dmidecode/dmidecode as alternative for kernel DMI

This implementation falls back to python-dmidecode (RHEL5.5+) if the kernel as no DMI support. Alternatively, if python-dmidecode is missing, we attempt to use the dmidecode binary (for RHEL5.4 and older) before giving up.

This fixes #376 and #1657 and also helps @lwade on RHEL5.5+.

Changes to allow WANT_JSON to allow JSON to non-Python modules

on untemplated variables in some rare cases.
Flush handlers before pre and post task sections change, but not between task and roles, as this seems
to be confusing to people (and not usually neccessary)
Update role example to show tag usage
Remove leftover debug statement in template code.
