service/fatal: Name FatalInfo structure members

Browse source 
Based off RE, most of these structure members are register values, which
makes, sense given this service is used to convey fatal errors.

One member indicates the program entry point address, one is a set of
bit flags used to determine which registers to print, and one member
indicates the architecture type.

The only member that still isn't determined is the final member within
the data structure.
