Now the attr tests are shell tests move the associated python and
configuration files. Update the installation build rules for the new
directories. Recycle the lib install rules for python files allowing
the explicit attr.py install line to be dropped.

d0d1dd628527c77d ("perf core: Add PERF_COUNT_SW_CGROUP_SWITCHES event")
Also change the expected sizeof(struct perf_event_attr) from 120 to 128 due to
fields being added for the SIGTRAP changes.
Addressing this perf build warning:

Add kernel AUX area sampling definitions, which brings perf_event.h into
line with the kernel version.
New sample type PERF_SAMPLE_AUX requests a sample of the AUX area
buffer. New perf_event_attr member 'aux_sample_size' specifies the
desired size of the sample.
Also add support for parsing samples containing AUX area data i.e.
PERF_SAMPLE_AUX.
Committer notes:
I squashed the first two patches in this series to avoid breaking
automatic bisection, i.e. after applying only the original first patch
in this series we would have:
# perf test -v parsing
26: Sample parsing :
--- start ---
test child forked, pid 17018
sample format has changed, some new PERF_SAMPLE_ bit was introduced - test needs updating
test child finished with -1
---- end ----
Sample parsing: FAILED!
#
With the two paches combined:
# perf test parsing
26: Sample parsing : Ok

We have a one of the event open fallback case in __perf_evsel__open
where we zero exclude_guest|exclude_host fields.
This means there's no way for attr tests to find out what's the right
value for those fields, so we need to check for both 0 and 1. Luckily we
still have other event parsing tests for those fields.

As the type is global through the framework and tests, the typo spawned
