Valgrind, ppc: Fix test for 32-bit testsuite.

The 32-bit testsuite executes the 64-bit class instruction prtyd.  This
instruction should not be tested in 32-bit mode.  The change also updates
the expected output for the test.  Note, 32-bit HW will generate a SIGILL
when the prtyd instruction is executed.  However, the 64-bit HW executing
a 32-bit application does execute the instruction but only the lower 32-bits
of the result are valid.  In general, the 64-bit class instructions should
not be executed in 32-bit binaries.

This fix accompanies the VEX fix in revision 2558 to add the 64-bit mode test
to make sure the 64-bit class instructions are only executed in 64-bit mode.
The VEX bugzilla is:

Bug 308573 - Internal Valgrind error on 64-bit instruction executed in
32-bit mode
