raphael: fingerprint: enable thinlto + whole program vtables optimiza…

…tion

We already enable with global lto, however we don't force on whole
program vtable optimizations for all. Due to visibility meeting
requirements for this optimization, this works fine. Whereas
not all modules using hidl_defaults meet requirements for this
optimization (which depends on LTO).
