Replace NR_SYSCALLS from asm/unistd.h and keep equivalent macro __NR_syscalls in uapi/asm/unistd.h and this will make a unified implementation across all the architecture and we can use a system call generation script to generate __NR_syscalls. While __NR_syscalls isn't strictly part of the uapi, having it as part of the generated header to simplifies the implementation.
