perf json: Add s390 transaction counter definition

'perf stat' displays transactional counters using flag -T on x86. On
s390 use a JSON file defined metric named transaction to achieve the
same result.

Output before:

none

Output after:

[root@s35lp76 perf]# ./perf stat -M transaction -- \
~/mytesttx 1 >/tmp/111

Performance counter stats for '/root/mytesttx 1':

1 tx_c_tend # 13.0 transaction
1 tx_nc_tend
11 tx_nc_tabort
0 tx_c_tabort_special
0 tx_c_tabort_no_special
