Subject: [PATCH v2 15/16] perf build: Remove test library from python shared object

With the attr.c code moved to a shell test, there is no need to link
the test code into the python dso to avoid a missing reference to
test_attr__open. Drop the test code from the python library.

With the bench and test code removed from the python library on my x86
debian derived laptop the python library is reduced in size by 508,712
bytes or nearly 5%.
