[packman] Change source and update libfprint-2-tod1-broadcom

[Max]

Hello! Sorry if this is the wrong email/channel to send these matters, 
let me know if that's the case.

I was debugging my fingerprint sensor not working, which I am now pretty 
sure comes down to windows having updated the on-device firmware but the 
driver libfprint-2-tod1-broadcom provided by packman expects older fw.

All that is not important, just background, but basically there's a new 
version of libfprint-2-tod1-broadcom: "5.15.377" (current in repo is 
"5.15.285").

The 377 version is not available at the source you are using (according 
to the upstream url provided: 
http://dell.archive.canonical.com/updates/pool/public/libf/libfprint-2-tod1-broadcom/) 
but *is* at Canonicals launchpad 
(https://git.launchpad.net/~oem-solutions-engineers/libfprint-2-tod1-broadcom/+git/libfprint-2-tod1-broadcom/) 
and from Broadcom directly 
(https://packages.broadcom.com/artifactory/dell-controlvault-drivers/).

I am not sure why the dell.archive is not updated (the 377 version is 
released to Ubuntu noble, jammy and next) and I'm not sure which is best 
to use, the Broadcom "artifactory" or Canonicals launchpad, I suspect 
you guys have a better idea about all that.

Note however! There is also a 6.x.x series if you look at Broadcoms 
index, however the 5.x and 6.x series support different devices. The 6.x 
series is usually packaged as "libfprint-2-tod1-broadcom-cv3plus" 
(referring to devices in "ControlVault 3 plus" series I presume are used 
in newer dell devices). It would be nice to add the cv3plus package but 
that's a separate matter. /Supported devices are visible in the udev rules./

Information about what is new/changed is nonexistent in this proprietary 
source, but on the windows side a CVE is mentioned, so the new 
version(s) are probably patches for this:

Updating the package (likely) helps me and anyone going from windows on 
their 2021-2024 era dell laptops get a working fingerprint sensor, not 
to mention patching the security issue and would be greatly appreciated!

Thank you in advance!
