sysvipc: Consolidate semtimedop s390
This patch consolidates the s390-32 semtimedop implementation by defining a arch-specific SEMTIMEDOP_IPC_ARGS to rearrange the arguments expected by s390 Linux kABI. The idea is to avoid have multiples semtimedop implementation changes for Linux v5.1 change to enable wire-up sysvipc support. Checked with a s390-linux-gnu and s390x-linux-gnu and checking that resulting semtimedop objects did not change. * sysdeps/unix/sysv/linux/ipc_priv.h (SEMTIMEDOP_IPC_ARGS): New define. * sysdpes/unix/sysv/linux/s390/ipc_priv.h: New file. * sysdeps/unix/sysv/linux/s390/semtimedop.c: Remove file. * sysdeps/unix/sysv/linux/semtimedop.c (semtimedop): Use SEMTIMEDOP_IPC_ARGS for calls with __NR_ipc.
