Running this test gives us a deprecation warning telling that this
machine type is no longer supported:

	Output: qemu-system-ppc: Machine type 'taihu' is deprecated:
incomplete, use 'ref405ep' instead

Moreover, this test fails to pass running in an IBM POWER host when
building QEMU with --disable-tcg.

Since the machine type is already being considered deprecated let's not
bother fixing the test with --disable-tcg. Remove test_ppc_taihu().
