File kdump-mounts.cc-Include-sys-ioctl.h.patch of Package kdump

From: Petr Tesarik <ptesarik@suse.com>
Date: Fri Mar 5 18:25:14 2021 +0100
Subject: mounts.cc: Include <sys/ioctl.h>
Upstream: merged
Git-commit: 9c47874dadcdb39fbb3cededc46bc32449f42374

Since the code uses ioctl(), it should include the corresponding
header file. This was not found before release, because including
the header file is not necessary with some glibc versions...
