[oe][meta-oe][PATCH] libp11: backport fix for missing p11_ver.h in installed headers

From: Daiane Angolini <[email protected]>

The installed public header libp11.h includes "p11_ver.h", but that
header is generated by configure (from p11_ver.h.in, via AC_CONFIG_FILES)
and was never listed in include_HEADERS, so it never gets installed.

Any consumer including <libp11.h> therefore fails to build. For example
rng-tools with PACKAGECONFIG "libp11" enabled:

| In file included from rngd_pkcs11.c:28:
| recipe-sysroot/usr/include/libp11.h:28:10: fatal error: p11_ver.h: No such file or directory
|    28 | #include "p11_ver.h"
|       |          ^~~~~~~~~~~
| compilation terminated.

Backport the upstream fix, which adds p11_ver.h to include_HEADERS. It
landed after the libp11-0.4.19 tag and is not part of any release yet,
so it cannot be picked up by a version upgrade.
