Repeated definition of PY_BUILTIN_HASHLIB_HASHES in configure.ac

[msprotz]

Bug report

Bug description:

The PY_BUILTIN_HASHLIB_HASHES variable is defined twice in configure.ac, which
results in the corresponding #define appearing twice in the autoconf
confdefs.h, which results in an unconditional compile error, meaning the test
isn't testing what it is supposed to test.
