Dominique Belhachemi da6870deba GH-49539: [C++][Parquet] Fix argument count check in parquet_scan (#49540) ...

### Rationale for this change
Running parquet-scan without arguments currently triggers a confusing IOError instead of showing how to use the tool.

### What changes are included in this PR?
Updated the argument validation from argc < 1 (always false) to argc < 2.

### Are these changes tested?
Yes. 

### Are there any user-facing changes?
Yes.

Old behavior:
$ parquet-scan
Parquet error: IOError: Failed to open local file ''. Detail: [errno 2] No such file or directory

New behavior:
$ parquet-scan
Usage: parquet-scan [--batch-size=] [--columns=...]
