[PATCH 2/2] libcamera: pipeline: virtual: Demote config file error message to debug

[Laurent Pinchart]

The virtual pipeline handler prints an error message when its
configuration file can't be opened. Not providing a configuration file
is the default method to disable virtual cameras, so this error is
confusing for users. Replace it with a debug message when the
configuration file is not found, and keep an error message when it
exists but can't be opened.
