Revert "rootfs.py: add more info to the warning message"

The reverted commit added a warning with the log line that triggered
the log check for error messages before the warning that states that
an error has been found in the log. However, the error line is output
by the call to bb.fatal() that follows immediately after the original
warning, which makes it redundant. Additionaly, having two warnings
contradicts the intent of commit 8dfdd329 where the log warnings were
tidied up.

This reverts commit f9cf31525fc885e1a0f65bd55654631257f87078.
