warning: short-form boolean option 'readonly' deprecated

[Agathe Porte]

[ Impact ]

The bug displays a warning when calling autopkgtest-buildvm-ubuntu-cloud. This is because the call to qemu uses a deprecated short version. The risk is that
in a future version of qemu the support for this short option is removed and
the tool stops working.

[ Test Plan ]

Use the patched autopkgtest package to run the
autopkgtest-buildvm-ubuntu-cloud command, and verify that the warning
is gone.

[ Where problems could occur ]

People running versions of qemu without the support for `readonly=on`
(if such version exist) may have the autopkgtest-buildvm-ubuntu-cloud
tool stop working.

[ Original Bug Report ]

When calling autopkgtest-buildvm-ubuntu-cloud on Ubuntu Noble, this warning appears:

Follow SRU template.

FYI: I'll soon cut an upstream autopkgtest release and merge, upload to Debian, merge in Ubuntu, and they this will be SRUd to Noble (and likely Jammy) under the autopkgtest SRU exception.

This bug was fixed in the package autopkgtest - 5.34ubuntu3

Added jammy as a target series.

Please assign yourself to the series if you want to take care of the SRU uploads. Thanks!
