[POWERPC] Never panic when taking altivec exceptions from userspace

At the moment we rely on a cpu feature bit or a firmware property to
detect altivec. If we dont have either of these and the cpu does in fact
support altivec we can cause a panic from userspace.

It seems safer to always send a signal if we manage to get an 0xf20
exception from userspace.
