libbsd: add upstream patch to fix musl build issue

Commit d879be3049598f35d7b959784e1a6c2811ba2036 enabled the build for non-glibc
toolchains and added a  patch from upstream to fix one remaining build issue
with musl.

The upstream patch defines the glibc specific macro `__GLIBC_PREREQ` in
`include/bsd/sys/cdefs.h`, but the patch does not include this header
file in `include/bsd/stdlib.h` which uses the macro.

Upstream did committed an earlier patch which adds this header inclusion
to `include/bsd/stdlib.h`. So, add this upstream patch as well to fix a
build error when building the hcitop tool from the not yet added package
bluez-alsa.

Note, that the upstream patch address the issue that `<sys/cdefs.h>` is
a non-portable header. However, this is not the issue which needs to be
fixed by this patch, but solely the needed inclusion of the
`include/bsd/stdlib.h` header file, to see the definition of
`__GLIBC_PREREQ`.

+Subject: [PATCH] Handle systems missing <sys/cdefs.h>
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This is a non-portable header, and we cannot expect it to be provided by
+the system libc (e.g. musl). We just need and rely on declaration that
+we have defined ourselves in our own <bsd/sys/cdefs.h>. So we switch to
+only ever assume that.

+Fixes: https://bugs.freedesktop.org/105281
