[PATCH 01/17] pylibfdt: Cast property length to Py_ssize_t

Commit 7d01bb1c5a1d ("libfdt: Fix build with python 3.10") took only half
of the upstream fix, dtc commit 383e148b70a4 ("pylibfdt: fix with Python
3.10"): it defines PY_SSIZE_T_CLEAN but leaves the length argument passed
to Py_BuildValue() as a plain int. With PY_SSIZE_T_CLEAN in effect the "y#"
and "s#" converters read a Py_ssize_t, so passing an int is undefined
behaviour that happens to work only where the two share a representation.

Take the remaining hunk so the typemap matches upstream and the subsequent
upstream imports apply verbatim.
