perf test: test case 'Setup struct perf_event_attr' fails on s390 on z/vm

perf test 17 'Setup struct perf_event_attr' fails on s390 z/VM guest,
using linux-next kernel.

Root cause is the fall-back from hardware counter cycles

perf_event_attr:
type 0 (PERF_TYPE_HARDWARE)
size 136
config 0 (PERF_COUNT_HW_CPU_CYCLES)
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ADDR|PERIOD|DATA_SRC
read_format ID|LOST

which returns -ENOENT on s390 z/VM guest. This causes the code to fall
back to software counter task-clock, as can be seen in the debug output:

------------------------------------------------------------
perf_event_attr:
type 1 (PERF_TYPE_SOFTWARE)
size 136
config 0x1 (PERF_COUNT_SW_TASK_CLOCK) <-here
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|ADDR|PERIOD|DATA_SRC
read_format ID|LOST

This succeeds on s390 z/VM guest.

This successful installation of the counter task-clock is not listed in
the expected results and the test case fails.

This is caused by commit eb2eac0c7b618033 ("perf evsel: Fallback to
"task-clock" when not system wide") which introduced fall back from
event 'cycles' to event 'task-clock'.

To fix this on s390 allow event number 0 (cycles) and event number 1
(task-clock) as expected result.

Output before:

# ./perf test -Fv 17
17: Setup struct perf_event_attr :
--- start ---
running './tests/attr/test-stat-group1'
unsupp './tests/attr/test-stat-group1'

excluded architecture list ['aarch64']
expected config=0, got 1
FAILED './tests/attr/test-record-graph-default' - match failure
---- end ----
Setup struct perf_event_attr: FAILED!
#

Output after:

# ./perf test -F 17
17: Setup struct perf_event_attr : Ok
