From 9b6c975ceb6e627783619d5dd544c94695223307 Mon Sep 17 00:00:00 2001
From: Alejandro Colomar <alx.manpages@gmail.com>
Date: Mon, 1 Aug 2022 21:13:37 +0200
Subject: Add mappings for <bits/types/siginfo_t.h>

siginfo_t members are implemented through macros and other stuff,
which is defined in that header, so map the header to the same
headers that siginfo_t is mapped.
