Subject: [PATCH 16/16] crypto: x86 - clean up poly1305-x86_64-cryptogams.S by 'make clean'

poly1305-x86_64-cryptogams.S is a generated file, so it should be
cleaned up by 'make clean'.

Assigning it to the variable 'targets' teaches Kbuild that it is a
generated file. However, this line is not evaluated while cleaning
because scripts/Makefile.clean does not include include/config/auto.conf.

Removing the ifneq-conditional, so this file is correctly cleaned up.
