Patched winedbg attempt

Winedbg loads the wrong debugging info for dlls where a native dll exists in
the prefix and the native dll is replaced with the built-in version.

For instance the lpImageName in the DEBUG_EVENT struct contains the path to the
C:\Windows\System32\somedll.dll but it is replaced with the built-in version
from the build directory (in my case) that is actually mapped in to memory. So
in this case winedbg loads the debug symbols from from the system directory and
not the one that is in the build directory.

However it looks like if calling NtQueryInformationFile with the file handle we
get the correct name to the loaded dll. See the attached patch how I solved the
issue.
