package_manager.py: get rid of ROOTFS_RPM_DEBUG in RpmPM()
This was undocumented, and it's better to just always enable
full debug output, as this allows immediate generation of logs
with full diagnostics when things go not as expected.
Also, change the output of dnf from note to debug level; this
does not affect what is written to log file, but does reduce the
verbosity of bitbake -v.
