Add exclude_* properties to apex arch-specific properties

The libcronet prebuilt JNI library doesn't exist for riscv64 yet.
Add exclude_* properties to apex arch-specific properties so that
the libcronet dependency can be excluded from the apex that contains
when the arch is riscv64 until it exists for riscv64.
