python37: updated to 3.7.1

Notable changes in Python 3.7.1

Starting in 3.7.1, Py_Initialize() now consistently reads and respects all of \ 
the same environment settings as Py_Main() (in earlier Python versions, it \ 
respected an ill-defined subset of those environment variables, while in Python \ 
3.7.0 it didn’t read any of them due to bpo-34247). If this behavior is \ 
unwanted, set Py_IgnoreEnvironmentFlag to 1 before calling Py_Initialize().

In 3.7.1 the C API for Context Variables was updated to use PyObject pointers.

xml.dom.minidom and xml.sax modules no longer process external entities by default.
