libstdc++: Avoid warning in std::format
With -Wmaybe-uninitialized -Wsystem-headers there's a warning about
creating a string_view from an uninitalized array. Initializing the
first element of the array avoids the warning.
libstdc++-v3/ChangeLog:
* include/std/format (__write_padded): Initialize first element
of array to avoid a -Wmaybe-uninitialized warning.
