S/390: Fix layout of struct sigaction_t
The ordering of some fields in struct sigaction on s390x (64bit)
differs compared to s390 and other architectures.
This patch adjusts this order according to the definition of
<glibc-src>/sysdeps/unix/sysv/linux/s390/bits/sigaction.h
Without this fix e.g. the call
sigaction( suspendSignalNumber, &sigusr1, null ) in thread.d
leads to setting the sa_restorer field to 0xffffffffffffffff.
In case a signal, the signal handler returns to this address
and the process stops with a SIGILL.
This was observable in several execution testcases on s390x:
libphobos.druntime/core/thread.d
libphobos.druntime_shared/core/thread.d
libphobos.thread/tlsgc_sections.d
libphobos.allocations/tls_gc_integration.d
