samples/bpf: add missing <linux/if_vlan.h>

Browse Source 
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
