Sam Atkins 4d2e18fb07 LibCore: Output invalid DateTime::to_string() specifiers as literals ...

While working on #13764 I noticed that DateTime::to_string() would just
return an empty String if the format included an invalid specifier
(eg `%Q`). This seems to be a mistake. POSIX date(1), which I believe
we are basing our implementation on, only replaces valid specifiers,
and any invalid ones get included as literals in the output.

For example, on Linux `date "+%Quiz"` returns "%Quiz", but we were
returning "".
