File shadow-bsc1230972-useradd-warning.patch of Package shadow.36083

Patch for bsc#1230972
Derived from upstream 1d8487d85105a8373408ce8d1470c5ed14fa6356

The upstream change modifies check_uid_range() in useradd.c to
print errors related to out-of-range UIDs to stderr instead of
stdout.

This patch backports check_uid_range(), including this change, to
shadow version 4.8.1, and adds a call to check_uid_range() in
main().
