Subject: [PATCH] bpo-31374: Include pyconfig.h earlier in expat (GH-11064)

Include <pyconfig.h> ealier in Modules/expat/xmltok.c to define
properly _POSIX_C_SOURCE. Python defines _POSIX_C_SOURCE as 200809L,
whereas <features.h> (included indirectly by <string.h>) defines
_POSIX_C_SOURCE as 199506L.
(cherry picked from commit cf247359d5b7082044eea1fa94b5211a172b1ff6)
