matchbox-session-sato: install GConf values directly instead of using schemas
Because both matchbox-session-sato and settings-daemon were attempting to
install their preferred values though schemas there was a race as to which ones
were used.
Revert matchbox-session-sato back to writing the values directly, adding a
dependency on gconf-native so that this can happen on the host.
