linux-user/sparc: Tidy syscall trap
Use TT_TRAP.
For sparc32, 0x88 is the "Slowaris" system call, currently BAD_TRAP
in the kernel's ttable_32.S. For sparc64, 0x110 is tl0_linux32, the
sparc32 trap, now folded into the TARGET_ABI32 case via TT_TRAP.
For sparc64, there does still exist trap 0x111 as tl0_oldlinux64,
which was replaced by 0x16d as tl0_linux64 in 1998. Since no one
has noticed, don't bother implementing it now.
