target/sparc: Loosen decode of STBAR for v8
Solaris 8 appears to have a bug whereby it executes v9 MEMBAR
instructions when booting a freshly installed image. According
to the SPARC v8 architecture manual, whilst bits 13 and bits 12-0
of the "Read State Register Instructions" are notionally zero,
they are marked as unused (i.e. ignored).
Fixes: af25071c1d ("target/sparc: Move RDASR, STBAR, MEMBAR to decodetree")
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/3097
