Subject: [PATCH] haydn: Patch xiaomi camera libraries

The modified library NOPs out the instruction to change binder
threadpool, allowing the library to load and camera to work on S.

Extend the pattern for cameraperf since "7c 00 00 94" occurs twice
to only NOP the configureRpcThreadpool call.
Output of llvm-objdump:
```
    3ad0: 7c 00 00 94  	bl	0x3cc0 <_ZdlPv@plt>
    3b10: 7c 00 00 94  	bl	0x3d00 <_ZN7android8hardware22configureRpcThreadpoolEmb@plt>
```
