Subsequent tests do require direct manipulation of the SIE control
block. This commit introduces the SIE control block definition for use
within the selftests.
There are already definitions of this within the kernel.
This differs in two ways.
* This is the first definition of this in userspace.
* In the context of the selftests this does not require atomicity for
the flags.
With the userspace definition of the SIE block layout now being present
we can reuse the values in other tests where applicable.

Test different variations of single-stepping into interrupts:
- SVC and PGM interrupts;
- Interrupts generated by ISKE;
- Interrupts generated by instructions emulated by KVM;
- Interrupts generated by instructions emulated by userspace.
