subversion: more reliable fix for APR 1.7.0

Subject: [PATCH] Get rid of apr_int64_t format string check in swig py
 configure.

This check relied on APR implementation details and broke with APR 1.7.0.
Rather than trying to guess a perfect format string to use, just use the
largest possible format and cast the argument accordingly.

Should fix build against APR 1.7.0 and later.

Suggested by: brane

* build/ac-macros/swig.m4: Remove code related to SVN_APR_INT64_T_PYCFMT.

* subversion/bindings/swig/python/libsvn_swig_py/swigutil_py.c
  (svn_swig_py_client_blame_receiver_func): Stop relying on the
   SVN_APR_INT64_T_PYCFMT constant from configure. Use "L" and
   acast to PY_LONG_LONG instead.
