[apparmor] [PATCH v2 39/42] libapparmor: Add macro for the gcc "unused" attribute

[Tyler Hicks]

As code is moved from the parser to libapparmor, the libapparmor code
base will need to have the "unused" macro defined. This macro will need
to be duplicated in the parser and libapparmor due to it being a
compiler-specific macro that shouldn't be exported from libapparmor.
