ntdll: Use default casemap and codepage file names if the value in registry is empty.

This helps to keep compatibility with old prefixes being reused for wine-5.0. Old prefixes in their registry have [System\\CurrentControlSet\\Control\\Nls\\Codepage] "37"="" [System\\CurrentControlSet\\Control\\Nls\\Language] "0409"="" and this leads to LCMapString(LCMAP_LOWERCASE/LCMAP_UPPERCASE) return garbage. This is a regression caused by 94a3add0. Signed-off-by: Dmitry Timoshkov <dmitry@baikal.ru> Signed-off-by: Alexandre Julliard <julliard@winehq.org>
