Each of the powerpc selftests runs with a timeout of 2 minutes by
default (see tools/testing/selftests/powerpc/harness.c).
But when tests are run with run_kselftest.sh it uses a timeout of 45
seconds, meaning some tests run OK standalone but fail when run with the
test runner.
So tell run_kselftest.sh to give each test 130 seconds, that should
allow the tests to complete, or be killed by the powerpc test harness
after 2 minutes. If for some reason the harness fails, or for the few
tests that don't use the harness, the 130 second timeout should catch
them if they get stuck.

Build breaks when executing make with run_tests for sub-folders
under powerpc. This is because, CFLAGS and GIT_VERSION macros are
defined in Makefile of toplevel powerpc folder.
make: Entering directory '/home/maddy/linux/tools/testing/selftests/powerpc/mm'
gcc hugetlb_vs_thp_test.c ../harness.c ../utils.c -o /home/maddy/selftest_output//hugetlb_vs_thp_test
hugetlb_vs_thp_test.c:6:10: fatal error: utils.h: No such file or directory
6 | #include "utils.h"
| ^~~~~~~~~
compilation terminated.
Fix this by adding the flags.mk in each sub-folder Makefile. Also remove
the CFLAGS and GIT_VERSION macros from powerpc/ folder Makefile since
the same is definied in flags.mk

Consistently testing system parameter access is a bit difficult by
nature -- the set of parameters available depends on the model and
system configuration, and updating a parameter should be considered a
destructive operation reserved for the admin.
So we validate some of the error paths and retrieve the SPLPAR
characteristics string, but not much else.
