selftests/bpf: Test per-call site function specialization
Add a test to ensure function call specialization is
done per-call site. Use bpf_dynptr_from_file that has
observably different behavior between its sleepable and
nonsleepable versions. The sleepable path fails in the
sleepable __kernel_read() call with -EIO, while the
nonsleepable fails in the page-cache lookup path with
-EFAULT. Test that whatever the order the nonsleepable
and sleepable calls are made in the program, both
call sites use the correct specialized kfunc.
