[FP4T-89][2] mfg_util

* Comment
There is no "USB Preference" notification after run command "adb shell mfg_util --do_factoryreset"

* Root Cause
Set persist.vendor.usb.config as "mfg" in --do_factoryreset

* Solution
Use persist.sys.usb.config in place of persist.vendor.usb.config and set persist.sys.usb.config as "none".

* Test Steps
1. Set inproduction flag
2. do factory reset in MMITest
3. Run "adb shell mfg_util --do_factoryreset" and "adb shell mfg_util --clear_inproductionflag"
4. DUT reboot
5. The USB Preference notification should be found when the USB cable is plugged in.

* Test Result
Pass
