    [MSPAINT] Don't use SIZEOF on a pointer
    
    Fixes GCC 8 warning:
    base/applications/mspaint/definitions.h:16:31: error: division 'sizeof (LPWSTR
{aka wchar_t*}) / sizeof (WCHAR {aka wchar_t})' does not compute the number of array
elements [-Werror=sizeof-pointer-div]
     #define SIZEOF(a)  (sizeof(a) / sizeof((a)[0]))
                         ~~~~~~~~~~^~~~~~~~~~~~~~~~
    base/applications/mspaint/main.cpp:134:55: note: in expansion of macro
'SIZEOF'
                     lstrcpyn(pon->lpOFN->lpstrFile, Path,
SIZEOF(pon->lpOFN->lpstrFile));
                                                           ^~~~~~
