Subject: [PATCH] s390: reintroduce expoline dependence to scripts

Expolines depend on scripts/basic/fixdep. And build of expolines can now
race with the fixdep build:

 make[1]: *** Deleting file 'arch/s390/lib/expoline/expoline.o'
 /bin/sh: line 1: scripts/basic/fixdep: Permission denied
 make[1]: *** [../scripts/Makefile.build:385: arch/s390/lib/expoline/expoline.o] Error 126
 make: *** [../arch/s390/Makefile:166: expoline_prepare] Error 2

The dependence was removed in the below Fixes: commit. So reintroduce
the dependence on scripts.
