Sample app replicating the bug

Thanks for the investigation. In order to make debugging and fixing this bug
a bit easier I've created a sample 16-bit application which replicates the bug.

It's worth to mention that 16-bit GetModuleFileName in the test returns
C:\WINNT\SYSTEM32\WINOLDAP.MOD under 32-bit XP. In Wine we have no a 16-bit
wrapper for ShellExecute16 to run 32-bit applications, so we either need to
introduce it, or somehow extend WinExec16/ShellExecute16 to return a proper
handler for 32-bit modules on which GetModuleUsage16 would work.
