[Buildroot] [PATCH 1/1] package/linux-pam: fix musl build

[Bernd Kuhls]

The bump to version 1.5.3 with buildroot commit
f8147e27cdac8f998ec6644a09ce4e8d62b6433c added the file patched.

Please note that the next version will include
https://github.com/linux-pam/linux-pam/commit/5fa961fd3b5b8cf5ba1a0cf49b10ebf79e273e96
which adds --enable-examples as configure option to disable examples.
This patch, although it would also fix the problem, is not added instead
to avoid autoreconf.

Fixes:

+
+termio.h is the old System V version of the interface header, and is
+only provided in glibc and dietlibc as far as I can tell.
+This fixes it to use the POSIX termios.h instead.

[Fabrice Fontaine]

Fix the following musl build failure raised since bump to version 1.6.0
in commit 7794fa4c4e1d19a245bb0367cde94560432a2bc5:

pam_namespace.c: In function 'process_line':
pam_namespace.c:649:41: error: 'SIZE_MAX' undeclared (first use in this function)
  649 |         if (count > UINT_MAX || count > SIZE_MAX / sizeof(uid_t)) {
      |                                         ^~~~~~~~
pam_namespace.c:41:1: note: 'SIZE_MAX' is defined in header '<stdint.h>'; did you forget to '#include <stdint.h>'?
   40 | #include "argv_parse.h"
  +++ |+#include <stdint.h>
   41 |
