I made two very small adjustments.

This breaks the build on Clang. Using { .cmd = 0 } instead is fine.

I have dropped this down to pv32pae pv64 hvm32 hvm64
The hvm32pse and hvm32pae environments are an identical ABI to hvm32, so
there is no point testing them all. The multiple paging options for
32bit HVM guests is only useful for testing pagetable related code.
