Mike Lockwood 0d23fec792 Add support for products overriding properties in /default.prop 
We need this to allow products to specify the default USB configuration,
and allow the build system to add adb to this configuration
for eng and userdebug builds.

For example:

PRODUCT_DEFAULT_PROPERTY_OVERRIDES += \
	persist.sys.usb.config=mtp
