[bpf-next 09/10] samples/bpf: use vmlinux.h instead of implicit headers in BPF test program

["Daniel T. Lee" <danieltimlee@xxxxxxxxx>]

This commit applies vmlinux.h to BPF functionality testing program.
Macros that were not defined despite migration to "vmlinux.h" were
defined separately in individual files.
