This is a variation on
https://lists.libcamera.org/pipermail/libcamera-devel/2024-January/040186.html
that embeds the checksums in the installed binary instead of
loading a configuration file. Post-processing the library like
this is of course rather icky, but testing with `ipa_verify` it
does appear to work. I have not tested this in a 'real' application
yet, and have not tested yet with more than a single module available,
as I wanted to collect feedback on the approach first.
