gdb: add program_space parameter to lookup_minimal_symbol

>From what I can see, lookup_minimal_symbol doesn't have any dependencies
on the global current state other than the single reference to
current_program_space.  Add a program_space parameter and make that
current_program_space reference bubble up one level.
