python3: upgrade to release 3.7.6

* external/python3/python-3.3.3-aix.patch.1:
most of it doesn't apply and AIX port isn't maintained anyway so
remove it for now
* external/python3/ubsan.patch.0:
apparently one of the files was removed
* 0001-3.6-bpo-17239-Disable-external-entities-in-SAX-parse.patch.1:
fixed upstream
* python3-osx-avoid-new-10.13.patch.1:
replace with simply passing ac_cv_func_utimensat=no to configure
* external/python3/python-3.5.4-ssl.patch.1:
project files to build OpenSSL removed upstream
* There have been changes to how python locates OpenSSL; new variables
OPENSSL_INCLUDES etc; it turns out that you have to pass one directory
to --with-openssl, as the variables cannot be passed
* libuuid.so.1 is a new dependency of the _uuid module
* libffi.so.6 is a new dependency of the _ctypes module (the bundled
copy of libffi for non-Darwin platforms was removed)
* python-3.3.0-pythreadstate.patch.1:
the PyThreadState functions have been changed such that
CppunitTest_services asserts when there is a PyThreadAttach on top of
PyThreadDetach on top of PyThreadAttach, i.e., 2 PyThreadState per
thread (PyGILState_Check() fails).  Instead of patching in additional
workarounds, change PyThreadAttach so that it re-uses an existing
PyThreadState if one exists for the thread.
