unix/coverage: Expand mp_printf coverage tests.

Browse Source 
Test 'l' and 'll' sized objects.  When the platform's `mp_int_t` is not 64
bits, dummy values are printed instead so the test result can match across
all platforms.

Ensure hex test values have a letter so 'x' vs 'X' is tested.

And test 'p' and 'P' pointer printing.
