linux-user/mips/o32: Drop sa_restorer functionality
The Linux kernel dropped support for sa_restorer on O32 MIPS in the release 2.5.48 because it was unused. See the comment in arch/mips/include/uapi/asm/signal.h. Applications using the kernels UAPI headers will not reserve enough space for qemu-user to copy the sigaction.sa_restorer field to. Unrelated data may be overwritten. Align qemu-user with the kernel by also dropping sa_restorer support.
