dalvik sysprop settings are optional
dalvik sysprop settings in these mk files are changed to optional ones
using the new 'a ?= b' syntax, to better express the intent that these
provides safe default values which will be used when they are set in
a product-specific mk file.
This is also in preparation for
I9c073a21c8257987cf2378012cadaeeeb698a4fb, which when lands will
prohibit duplicated sysprop assignments.
