gconf: fix saving of settings when config folder doesnt exist

In some circumstances, gconf isn't able to save configurations
because ~/.config folder aka root_dir doesn't exist.

For example when saving settings using matchbox-appearance,
the following error is shown:

GConf Error: Configuration server couldn't be contacted: D-BUS error:
Can't overwrite existing read-only value: Value for
`/desktop/poky/interface/font_name' set in a read-only source at the
front of your configuration path

This issue was not seen before because ~/.config directory is shared
between several packages and one of those packages usually creates it
by the time gconf wants to use it.

This patch makes sure that gconf creates the .config directory if it
doesn't exist, along with the gconf directory inside it.
