selftests/powerpc: Give all tests 2 minutes timeout

Each of the powerpc selftests runs with a timeout of 2 minutes by
default (see tools/testing/selftests/powerpc/harness.c).

selftests/powerpc: Give all tests 2 minutes timeout

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.
