Move some exception strings to PROGMEM (#5050)

Browse Source 
The memory allocation failure message was accidentally stored in RAM
and not in PROGMEM.

panic() did not place the __FILE__ string in PROGMEM, either.

Move both to PROGMEM, save ~64 bytes of heap (depends on size of path
of the Arduino core library).
