[meta-oe][PATCH] package_manager.py: set dnf always debug verbosity

[Paulo Neves <ptsneves@gmail.com>]

Removed an undocumented configuration
variable called ROOTFS_RPM_DEBUG. This configuration
toggled the verbosity of the dnf command. We now have
verbosity permanently turned on and instead of
directing this verbosity to bb.note we direct it
to bb.debug.

Having the verbosity enabled will allow to watch
the progress of the dnf package manager during the
do_rootfs task with the debug enabled in bitbake.

An example of the impact from enabling the
verbose output.

bitbake core-image-minimal
rm -rf tmp
bitbake core-image-minimal
