The path detection for "Setup struct perf_event_attr" test is brittle
and leads to the test frequently not running. Running shell tests is
reasonably robust, so make the test a shell test. Move the test files
to reflect this.
Before, if you build perf like `make -C tools/perf O=/tmp/perf` then
run the built perf test for the "Setup struct perf_event_attr" it
skips (causing the tests to bitrot, fixes to be sent, etc.):
```
$ sudo /tmp/perf/perf test -vv perf_event_attr
capget syscall failed (No such file or directory - 2) fall back on root check
17: Setup struct perf_event_attr:
17: Setup struct perf_event_attr:
--- start ---
test child forked, pid 806601
Using CPUID GenuineIntel-6-8D-1
---- end(-2) ----
17: Setup struct perf_event_attr : Skip
```
The issue is around the path set up, the test has a few path
expectations but they are brittle as shown above. While we could
endeavour to set up the path in C code, it makes sense to migrate the
test to a shell test due to the tests smaller size, ease of
environment variable manipulation, existing perf test support for
better path setup, etc. Ie let's not reinvent the shell test
infrastructure that handles python tests for the sake of one C test.
After this change:
```
$ sudo /tmp/perf/perf test attribute
76: Perf attribute expectations test : Ok
```

perf test: Add a shell wrapper for "Setup struct perf_event_attr"
perf test: Remove C test wrapper for attr.py
perf test: Move attr files into shell directory where they are used
