Correct types for various PyArg_ParseTuple/Py_BuildValue calls

Debian's [mips] build failed one of the font tests:

    FAIL: test_sprite_map (kitty_tests.fonts.Rendering)
    ----------------------------------------------------------------------
    Traceback (most recent call last):
      File "/<<PKGBUILDDIR>>/kitty_tests/fonts.py", line 48, in test_sprite_map
        self.ae(test_sprite_position_for(0, 1), (0, 1, 1))
        self = <kitty_tests.fonts.Rendering testMethod=test_sprite_map>
    AssertionError: Tuples differ: (0, 0, 0) != (0, 1, 1)

    First differing element 1:

    + (0, 1, 1)
    ?     ^  ^

This was due to test_sprite_position_for() using the "I" code to parse
into an unsigned short.  Since mips is big endian, the "wrong" byte was
stored into extra_glyphs.data.

This commit changes all similar data type mismatches that were found
from auditing calls to PyArg_ParseTuple/Py_BuildValue.
