Adds a couple of perf_event_attr tests for the fix introduced in [1].
The tests check that the correct sample_period value is set in the
struct perf_event_attr of the arm_spe events.

I tested this patch with two commands:
# PERF_TEST_ATTR=/tmp /usr/bin/python2 ./tests/attr.py -d ./tests/attr/ \
-p ./perf -vvvvv -t test-record-spe-period
# PERF_TEST_ATTR=/tmp /usr/bin/python2 ./tests/attr.py -d ./tests/attr/ \
-p ./perf -vvvvv -t test-record-spe-period-term
Both testing can pass on Hisilicon D06 board.
One question: I'm a bit concern this case will fail on some Arm64
platforms which doesn't contain Arm SPE modules. E.g. below commands
will always fail on Arm64 platforms if SPE module is absent. So I am
wandering if we can add extra checking ARM SPE event is existed or not?
# ./perf test list
17: Setup struct perf_event_attr
# ./perf test 17
Thanks,
Leo

The test reports "unsupported" if the return code and the 'ret' field don't match.
When I unload the SPE module:
running './tests/attr//test-record-spe-period-term'
test limitation 'aarch64'
unsupp './tests/attr//test-record-spe-period-term'
