Always use aapt2 --no-static-lib-packages

--no-static-lib-packages was removed when compiling libraries with
use_resource_processor: true enabled, but that caused problems resolving
attributes of styleables.  androidx.preference declares the "icon"
attribute inside a <declare-styleable>, but doesn't give it a format.
aapt2 refuses to create a new attribute for this case (b/131100106),
but without --no-static-lib-packages aapt2 can resolve the attribute
from the one defined in androidx.appcompat.
