selftests: bpf: Replace sizeof(arr)/sizeof(arr[0]) with ARRAY_SIZE

The ARRAY_SIZE macro is more compact and more formal in linux source.

bpf/selftests: Test fentry attachment to shadowed functions

Adds a new test that tries to attach a program to fentry of two
functions of the same name, one located in vmlinux and the other in
bpf_testmod.

To avoid conflicts with existing tests, a new function
"bpf_fentry_shadow_test" was created both in vmlinux and in bpf_testmod.

The previous commit fixed a bug which caused this test to fail. The
verifier would always use the vmlinux function's address as the target
trampoline address, hence trying to create two trampolines for a single
address, which is forbidden.

The test (similarly to other fentry/fexit tests) is not working on arm64
at the moment.
