validates that bpf_get_func_ip returns proper values from
both uprobe and return uprobe.

With CONFIG_X86_KERNEL_IBT enabled the test for kprobe with offset
won't work because of the extra endbr instruction.
As suggested by Andrii adding CONFIG_X86_KERNEL_IBT detection
and using appropriate offset value based on that.
Also removing test7 program, because it does the same as test6.

bpf_prog_test_run is being deprecated in favor of the OPTS-based
bpf_prog_test_run_opts.
We end up unable to use CHECK in most cases, so replace usages with
ASSERT_* calls.

Allow to specify decimal offset in SEC macro, like:
SEC("kprobe/bpf_fentry_test7+5")
Add selftest for that.

Adding test for bpf_get_func_ip in kprobe+ofset probe.
Because of the offset value it's arch specific, enabling
the new test only for x86_64 architecture.
