std.zig.system: always use qemu-sparc32plus for 32-bit sparc in getExternalExecutor()

qemu-sparc32plus can run both traditional 32-bit binaries and 32-bit "plus"
(32-bit ABI on 64-bit kernel) binaries because it has a wider array of emulated
CPU types. By contrast, qemu-sparc simply cannot emulate v9 instructions that
appear in 32-bit binaries. This is a problem for us because we set our baseline
to v9 even for 32-bit; v8 hardware is borderline archaic and lacks atomic
primitives that e.g. glibc requires.
