binder: fix sender_euid type in uapi header
The {pid,uid}_t fields of struct binder_transaction were recently replaced to use kernel types in commit 169adc2b6b3c ("android/binder.h: add linux/android/binder(fs).h to UAPI compile-test coverage"). However, using __kernel_uid_t here breaks backwards compatibility in architectures using 16-bits for this type, since glibc and some others still expect a 32-bit uid_t. Instead, let's use __kernel_uid32_t which avoids this compatibility problem.
