utils/generate-cyclonedx: use argparse defaults help formatter

Browse Source 
The argparse library documentation [1] suggest the usage of
'ArgumentDefaultsHelpFormatter' in the ArgumentParser declaration to
show the default value of every arguments.

Use this to avoid declaring this value ourself which possibly gets
outdated with the actual default value.

Note that this also adds an unnecessary default: FALSE to the --virtual
option, but that's a minor annoyance.
