Search debugfile directly in debug-file-directory if specified

[Mateusz Tabaka <8tab at wp dot pl>]

Hi, When I set debug-file-directory, searching for debuglink doesn't 
work when it is located directly in that directory 
(<debug-file-directory>/debuglink). This patch fixes this issue.

Thanks,
Mateusz.
