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.
