efl/emotion: fix usage of eina_prefix, add checkme file.

we were using "" for locale that made eina_prefix think that we did
not had a common prefix.

take the time and add a magic file "checkme" to be checked at runtime
to validate stuff.

also made the binaries be searched in MODULE_ARCH namespace.
