[LTP] [PATCH 7/7] Add lsm_set_self_attr01 test

Hi Andrea,

As I wrote at 2nd patch [1], booting with lsm= breaks all but
lsm_list_modules0[12].c. E.g. in this patch:

# ./lsm_set_self_attr01
tst_buffers.c:57: TINFO: Test is using guarded buffers
tst_test.c:1893: TINFO: LTP version: 20240930-146-gccd20cd77

tst_test.c:1728: TINFO: Timeout per run is 0h 00m 30s

lsm_common.h:51: TINFO: smack is running
lsm_set_self_attr01.c:110: TBROK: Can't read LSM current attribute

FYI lsm= bot parameter causes setup (at least on Tumbleweed kernel config):
$ cat /sys/kernel/security/lsm
lockdown,capability,ima,evm

Kind regards,
Petr
