perf symbols: Check return value of filename__read_debuglink()
When dso__read_binary_type_filename() called, it doesn't check the return value of filename__read_debuglink() so that it'll try to open the debuglink file even if it doesn't exist. Also fix return value of the filename__read_debuglink() as it always return -1 regardless of the result.
