libtirpc: Fix build error due to missing stdint.h inclusion

Add patch to fix following error:
| ../../libtirpc-1.0.1/src/xdr_sizeof.c:93:13: error: 'uintptr_t' undeclared (first use in this function); did you mean '__intptr_t'?
|   if (len < (uintptr_t)xdrs->x_base) {
|              ^~~~~~~~~

This error occurs with the latest glibc master version (during the testing I had
glibc commit 92bd70fb85bce57ac47ba5d8af008736832c955a), but doesn't occur with
version 2.25.

Patch includes stdint.h to provide uintptr_t.

It has been submitted upstream:
https://sourceforge.net/p/libtirpc/mailman/message/35850276/
