wayne-common: Support Alipay fingerprint payment

 * IFAA manager is based on OnePlusOSS, but adapted for Xiaomi's mlipay
   interface.Also hardcode model detection to pass Alipay check.
 * vendor.xiaomi.hardware.mtdservice@1.0.so is not actually used, thus
   patchelf to drop it rather than shipping a blob.
 * Modify libmlipay.so to allow load firmware from vendor
