s390: opt into HAVE_COPY_THREAD_TLS
This the s390 version of commit c1bd55f922a2d ("x86: opt into
HAVE_COPY_THREAD_TLS, for both 32-bit and 64-bit").
Simply use the tls system call argument instead of extracting the tls
argument by magic from the pt_regs structure.
See commit 3033f14ab78c3 ("clone: support passing tls argument via C
rather than pt_regs magic") for more background.
