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.
