MeeGo support

This commit consists of the initial work to include MeeGo as a ported
distribution for systemd.

The majority of the changes are small configuration additions to auto
tools, so that MeeGo is identified as a valid distribution option.

Some small deviations will be noticed between the configuration of MeeGo
and other distributions. As MeeGo is a distribution striving for
compliancy to support its near embedded attributes and target users,
there is less user configuration options available by default. Most
services will be enabled by systemd as part of the distribution
requirements, and as such most links and service files will be pre-setup
for the MeeGo distribution. As much of this is going to be done within
the MeeGo distribution packaging this is still noteworthy to mention, as
it explains why in systemd you will observe configuration differences
where the MeeGo distribution removes all links in the pkgsysconfdir for
instance.  MeeGo will be user configurable if there is desire, but most
services will be enabled by the distribution as designated by the MeeGo
compliancy standards.

Other changes are in source to add such areas as meego-release defined
in utils, and hostname in hostname-setup, defining vconsole-setup,
localizations and rescue additions as needed.

As this is all ground work, MeeGo will continue to strive for complete
compatibility.
