gnu: python-wxpython: Apply patch to fix TypeError exceptions.

This is caused by Python 3.10's new behavior of native extension now rejecting
float values as input when the expected type is an integer.

* gnu/packages/patches/python-wxwidgets-type-errors.patch: New patch.
* gnu/local.mk (dist_patch_DATA): Register it.
* gnu/packages/wxwidgets.scm (python-wxpython) [source]: Apply it.  Delete
trailing #t.
[arguments]: Delete trailing #t.
