ipc: fix semtimedop for generic 32-bit architectures
commit 78e05972c5e6c8e9ca4c00ccc6985409da69f904 upstream.
As Vincent noticed, the y2038 conversion of semtimedop in linux-5.1
broke when commit 00bf25d693e7 ("y2038: use time32 syscall names on
32-bit") changed all system calls on all architectures that take
a 32-bit time_t to point to the _time32 implementation, but left out
semtimedop in the asm-generic header.
This affects all 32-bit architectures using asm-generic/unistd.h:
h8300, unicore32, openrisc, nios2, hexagon, c6x, arc, nds32 and csky.
The notable exception is riscv32, which has dropped support for the
time32 system calls entirely.
