Incorrect errors reported on some libexec files with 'odin check stdio.odin -no-entry-point -file'

[Dima-369]

I noticed that using -file gives false positives for:

/opt/homebrew/Cellar/odin/2024-07/libexec/core/c/libc/stdio.odin

OdinBuildProcessRunner.java runs it like this:

odin check stdio.odin -no-entry-point -file

But using odin check . on the entire libc directory works correctly and does not report any errors. Let's drop -file and always check the directory the containing file is in, maybe?

Oh, I actually thought that this might happen and also thought I tested against it. But ok, the fix should be a very quick. This might be worth another release.

Edit: Yes, I think checking the dir instead of the file should be fine.

With your recent commits, this works fine in all the handful of files, I tested with.
