dbghelp: Fix read beyond end of field in module_get_debug.

[Robert Shearman]

pair->effective->module is of type IMAGEHLP_MODULEW64 and the ImageName 
field is 256 WCHARs long. However, idslW64 is of type 
IMAGEHLP_DEFERRED_SYMBOL_LOADW64 and the FileName field is MAX_PATH + 1 
(261) WCHARs long.

Therefore, it could read beyond the end of the ImageName field in the 
memcpy call. Although, benign in this case, it isn't good form so the 
size passed to the memcpy call is changed to use the smaller of the two 
fields.
