samples/bpf: add missing <linux/if_vlan.h>
This fixes build error regarding redefinition:
CLANG-bpf samples/bpf/parse_varlen.o
samples/bpf/parse_varlen.c:111:8: error: redefinition of 'vlan_hdr'
struct vlan_hdr {
^
./include/linux/if_vlan.h:38:8: note: previous definition is here
So remove duplicate 'struct vlan_hdr' in sample code and include if_vlan.h
