kernel32: Use the full path as an argument to winevdm.exe.

When starting a 16-bit process using CreateProcess() which resides in a subdirectory, the directory is changed but winevdm.exe still attempts to look for the whole path. Thus attempting to start "install\setup.exe" will cause winevdm.exe to look for "install\install\setup.exe", which fails.
