[issue10182] match_start truncates large values

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I analyzed all 1-valued usages of Py_BuildValue and found similar bags only in Modules/_sre.h. Here is a patch.

Bugs should be evident on big-endian platform with sizeof(int) < sizeof(size_t) or sizeof(long) < sizeof(size_t). Standard tests should fail on such platforms.
