[PATCH bpf 1/3] bpf: syscall to start at file-descriptor 1

This patch change BPF syscall to avoid returning file descriptor value zero. As mentioned in cover letter, it is very impractical when extending kABI that the file-descriptor value 'zero' is valid, as this requires new fields must be initialised as minus-1. First step is to change the kernel such
