Ihor Solodrai 0cecd492f5 libbpf: Remove extern declaration of bpf_stream_vprintk() 
An issue was reported that building BPF program which includes both
vmlinux.h and bpf_helpers.h from libbpf fails due to conflicting
declarations of bpf_stream_vprintk().

Remove the extern declaration from bpf_helpers.h to address this.

In order to use bpf_stream_printk() macro, BPF programs are expected
to either include vmlinux.h of the kernel they are targeting, or add
their own extern declaration.
