Timothy Redaelli 0c4d144a98 Remove dependency on python3-six 
Since Python 2 support was removed in 1ca0323e7c29 ("Require Python 3 and
remove support for Python 2."), python3-six is not needed anymore.

Moreover python3-six is not available on RHEL/CentOS7 without using EPEL
and so this patch is needed in order to release OVS 2.13 on RHEL7.

# To add new entries to the bugtool, you need to:
#
# Create a new capability. These declare the new entry to the GUI, including
# the expected size, time to collect, privacy implications, and whether the
# capability should be selected by default. One capability may refer to
# multiple files, assuming that they can be reasonably grouped together, and
# have the same privacy implications. You need:
#
# A new CAP_ constant.
# A cap() invocation to declare the capability.
#
# You then need to add calls to main() to collect the files. These will
# typically be calls to the helpers file_output(), tree_output(), cmd_output(),
# or func_output().
