Use original name instead of yet another temp file

[zilti]

Use the original file name (since that is, according to the docstring, what phpstan-normalize-path wants) instead of creating yet another temporary file that will confuse interpreters etc.

@zilti Thank you. However, this patch is not accepted because the analysis results will not be displayed unless the file is saved. Please suggest another method.

Well, I don't know enough about the Flycheck internals. But my alternative suggestion would be to have both be temp files outside the original file's directory. At that point the question is why this extra roundtrip to some custom function is needed in the first place.
