[PATCH, committed] jit: fix crash in memento_of_new_string_literal::make_debug_string

[David Malcolm]

Fix a crash due to missing a format string in a printf-style call,
when printing a string literal that contains formatting characters.

Seen on aarch64, where the patch takes jit.sum to:
        # of expected passes            7514
and no failures.

Committed to trunk as r219851.

	* jit-recording.c
	(gcc::jit::recording::memento_of_new_string_literal::make_debug_string):
	Add missing format string.
