ro.com.android.dataroaming in device.mk is optional
The final value for the system property is in device_vendor.mk
Change the setting in device.mk as optional to explicitly mark that
the value there can be overridden. This also is in preparation for
I9c073a21c8257987cf2378012cadaeeeb698a4fb where duplicated
(non-optional) sysprops is prohibited.
