the script shows an incorrect file name, I check the wrong file first, then
I find the script did not print the current reading file name.
Fix this to prevent others from wasting their time on this.
The new error message:
```
[1/179] Generating syscalls.json, struct_tags.json
Error decoding zmk/.../altera_msgdma.c (included in zephyr/.../ethernet.c)
