rip-headers.sh: preserve arch/*/kernel/syscalls for all arches

Noticed by Jer as install failure:
    scripts/Makefile.build:42: arch/parisc/kernel/syscalls/Makefile: No such file or directory
    make[1]: *** No rule to make target 'arch/parisc/kernel/syscalls/Makefile'.  Stop.
    make: *** [arch/parisc/Makefile:168: archheaders] Error 2

The change generalises s390 tblgen inclusion for all arches.
