Fixed -W cmdline option handling.

Reverted part of https://github.com/cc65/cc65/commit/3157e4be1ec7f2a5ac61ca45b232cd07c5e30483 as it actually introduced a regression.

It doesn't make sense to check for Arg[3] == '\0' _before_ checking Arg[2] != '\0'. This made the Win32 builds fail to correctly parse e.g. cl65 -W unused-var test.c
