attr tests
Now we'll see the command being run and if it fails, the fields that had
unexpected values and the expected values, example testing a problem in the
next patch:
# perf test -v 13
13: struct perf_event_attr setup :
--- start ---
SNIP
running 'PERF_TEST_ATTR=/tmp/tmpDNIE6M /home/acme/bin/perf record -o /tmp/tmpDNIE6M/perf.data --group -e cycles,instructions kill >/dev/null 2>&1' ret 0
running 'PERF_TEST_ATTR=/tmp/tmpV5lKro /home/acme/bin/perf stat -o /tmp/tmpV5lKro/perf.data -dd kill >/dev/null 2>&1' ret 1
expected config=3, got 65540
expected exclude_guest=1, got 0
FAILED '/home/acme/libexec/perf-core/tests/attr/test-stat-detailed-2' - match failure
---- end ----
struct perf_event_attr setup: FAILED!
#
While in the past we would see at the '-v' level many more messages for the
fields that matched, something we may want to see only in the '-vv' log level.
Keeping the 'running' messages so that we can see the tools tests that
succeeded so that we can compare it to the one that failed, helping pinpointing
the command line switch combo that leads to the problem.

Currently if there's 'Unsup' exception raised, we do not clean up the
temp directory. Solving this by adding 'finally' to make the cleanup in
any case.

Since we allow multiple values in event field assignment, there's no
need for 'optional' field.. old version removal leftover.
Adding some comments into attr.py script regarding the test event load.

Currently the 'watermark' field is coded as 'watermask'.
As the type is global through the framework and tests, the typo spawned
no error.

The idea is run perf session with kidnapping sys_perf_event_open
function. For each sys_perf_event_open call we store the perf_event_attr
data to the file to be checked later against what we expect.
You can run this by:
$ python ./tests/attr.py -d ./tests/attr/ -p ./perf -v
v2 changes:
- preserve errno value in the hook
