[ptxdist] [PATCH] libcamera: install IPA proxy workers unconditionally

[Matthias Fend <matthias.fend@emfend.at>]

If an IPA module is unsigned or the signature is invalid, the IPA is
isolated and runs in a separate process.
These so-called proxy workers must be installed for each activated
pipeline, even if the corresponding IPA module is not selected. Otherwise,
an out-of-tree IPA module (these are unsigned) cannot be used.
Since there is not an IPA module or associated proxy for every pipeline
(e.g. simple, uvcvideo), an additional list is required.
