Julia Kreger 69187bae3f Provide an ability to disable serial console injection
By default, we attempt to inject a serial console, which may, or may not
be needed, for example, Centos Stream 9 cloud images already configure
a console setting, and repeating it just might be undesirable and cause
workload performance degredation if the kernel or an application has to
report anything to a console.

This change generally results in original console entries being preserved,
which might actually be a bug and get fixed in a latter patch.

Generally, users of dib *should* likely be specific what they want to do
with their console setting, and without setting the new
DIB_BOOTLOADER_USE_SERIAL_CONSOLE paramter to false, the default will
be adhered to, and any pre-existing serial console entries will *not* be
de-duplicated from the base image. That too is *likely* a bug, but a
harder one to fix.
