klte-common: Enable single/dual SIM support with fragments * klte-common has to support both single- and dual-SIM devices, and there are multiple devices of each kind. It makes most sense to provide fragments in the -common tree that these devices can inherit to configure HIDL manifest, system properties, audio support, and any additional services necessary for MSIM support.
