[yocto] [PATCH][meta-selinux] audit/auvirt: get inline functions work with C99

[wenzong.fan at windriver.com]

From: Wenzong Fan <wenzong.fan at windriver.com>

This fixes link errors:

  auvirt.c:484: undefined reference to `copy_str'
  auvirt.c:667: undefined reference to `is_resource'

As gcc5 doc about "Different semantics for inline functions":

  > C99 extern inline: An externally visible function is generated; \
  > same as GNU89 inline.

  > To fix this, either mark the function foo as extern, or add the \
  > following declaration: extern inline int foo (void);
