Move modem_svc_sit from gs101 to bluejay

Module `modem_svc_sit` is not valid unless:
* USES_LASSEN_MODEM is true
* BOARD_WITHOUT_RADIO is NOT true (or NOT set)

Devices in gs101 family will set "USES_LASSEN_MODEM := true"; however,
not evevy gs101 device disables BOARD_WITHOUT_RADIO.

This commit defines PRODUCT_PACKAGES `modem_svc_sit` because it is
converted from bp by moving the if-statement constrain from the module
level to device level, device-bluejay.mk in this case.
