[PATCH] eventdev: drop custom OS defines

[Bruce Richardson <bruce.richardson@intel.com>]

The eventdev library doesn't need to put in place its own defines for
Linux and BSD. There are already defines for the OS environment in
rte_config.h that can be re-used, but since these are just for
identifying Linux/non-Linux, we can just check for the standard define
'__linux__' instead.
