hoist `-Wl,--pack-dyn-relocs=android` to the driver

[DanAlbert]

Some form of relocation packing will also be available by default. I can't tell if any of our tools actually do that though.

#909 adds android+relr this for 28+. With this, we've tacilty established in upstream that Android is using lld by default. Can we host the flag for 23-28 as well?

I'd be in favor of that for sure.
