osmo_static_assert: Put back the typedef in the code
In OSX the int declares linkage and for libosmo-abis we have
two static asserts with the same name in two different compilation
units. When adding the "unused" attribute I removed the typedef.
I verified with a gcc 4.9.2 that no new warnings will be shown
when compiling libosmo-abis.
