genksyms: properly consider EXPORT_UNUSED_SYMBOL{,_GPL}() 



Despite being unused these should also get a CRC calculated.
Primarily I view this as a consistency thing.  But I also think this is
one of the reasons why __crc_* need to be weak (which I think should be
avoided, and hence we should have the goal to eliminate this so that
failure to calculate a proper CRC for a symbol causes the build to fail).
