samples/bpf: Fix a compilation error with fallthrough marking
Compiling samples/bpf hits an error related to fallthrough marking.
...
CC samples/bpf/hbm.o
samples/bpf/hbm.c: In function ‘main’:
samples/bpf/hbm.c:486:4: error: ‘fallthrough’ undeclared (first use in this function)
fallthrough;
^~~~~~~~~~~
The "fallthrough" is not defined under tools/include directory.
Rather, it is "__fallthrough" is defined in linux/compiler.h.
Including "linux/compiler.h" and using "__fallthrough" fixed the issue.
