[apparmor] [patch] parser: use htoleXX functions instead of testing for endianess

This patch applies on top of John's last submission. It makes use of
the htoleXX() functions (see endian(3)) defined as part of endian.h
(already included in parser_interface.c), instead of defining a
function differently based on the detection of endian related macros.
This fixes a build failure experienced on powerpc with John's patch set
applied.
