selftests/bpf: fix stacktrace_build_id with missing kprobe/urandom_read
Kernel function urandom_read is replaced with urandom_read_iter.
Therefore, kprobe on urandom_read is not working any more:
[root@eth50-1 bpf]# ./test_progs -n 161
test_stacktrace_build_id:PASS:skel_open_and_load 0 nsec
libbpf: kprobe perf_event_open() failed: No such file or directory
libbpf: prog 'oncpu': failed to create kprobe 'urandom_read+0x0' \
perf event: No such file or directory
libbpf: prog 'oncpu': failed to auto-attach: -2
test_stacktrace_build_id:FAIL:attach_tp err -2
161 stacktrace_build_id:FAIL
Fix this by replacing urandom_read with urandom_read_iter in the test.
Fixes: 1b388e7765f2 ("random: convert to using fops->read_iter()")
