Convert download_fileobj logline from info to debug.

For the download_fileobj operation, which has been overridden in inject, a succesful transfer generates a logline that looks something like this:
2024-07-28 15:52:43,308 INFO inject "Downloaded file from xxxxxxx/TYPO3_INSTALLATION/eudsamf.ibog.xxxxxx.xx_1722174744-ZQHDBEGI.db.gz"

Atleast for my project, this logline will mostly cause confusion.
This change converts this to debug, which is consistent with other logging in inject.py.
