date: escape control characters in invalid date messages like GNU

[anasbekheit]

The "invalid date" message printed the input as-is, so tabs, CR, backspace
and ESC in a -d argument or a -f line went to the terminal raw, and a file
could inject escape sequences. GNU escapes them.

GNU testsuite comparison:

Skipping an intermittent issue tests/date/resolution (passes in this run but fails in the 'main' branch)

[sylvestre]

please add a test in tests/by-util/test_date.rs for tab/CR/ESC with -d and with a -f file

[sylvestre]

the non-UTF-8 locale branch (quote + non-ASCII octal) isn't tested either, could you add one with LC_ALL=C?
