[MTR-MTQ] Quectel support for sms-utils

- Added new "manufacturer" field to the "global_core" structure
- Added the "atcmd_plus_gmi_read()" function to fetch manufacturer identification
- Added a call to the "atcmd_plus_gmi_read()" in "sms_atcmd_init()"
- Added "is_telit_model()" and "is_quectel_model()" functions to pick
  a proper manufacturer-specific command in "atcmd_plus_iccid_read()" and,
  possibly, other commands in the future
- Tabs VS spaces. This project uses tabs
