ubi-utils-klibc_1.5.2: fix build for qemuarm

Building the recipe with TUNE_FEATURES = "aarch64" and TARGET_FPU = ""
fails. See patch headers for more details.

Patch sent upstream for master, here rebased for 1.5.2.
Tested runtime on armv5.

While there backport one more patch fixing warnings in libmtd.c and
move the patches in their specific dir, preparing for v2.0.1.

+From b668cb75cb7e72ff92055209130d4cd4b3cacbdb Mon Sep 17 00:00:00 2001

+Subject: [PATCH 4/9] Restore compatibility to dietlibc, klibc, musl libc after
+ commit 4f1b108
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Each C library has their own way to define off_t, and the <features.h>
+header is nonstandard and specific to the GNU libc and those that clone
+it (uClibc). Fefe’s dietlibc uses different flags, and klibc always uses
+a 64-bit off_t (like the BSDs); musl libc cannot be recognised using cpp
+instructions, so we assume 64 bit there (and on unknown C libraries) and
+leave it to the user to submit a follow-up fix if we guess wrong. I also
+added a static assertion to verify the 64 bit guess is correct.
+
+It would be really better using a configure script for this instead.
+
+Fixes:
