Add missing client build dependency in Fedora.

[Moxie07]

What

Add missing client build dependency in Fedora Linux.

Why

Because when i tried to build it after installing the dependency showed in document, meson gives me the following error:
app/meson.build:115:20: ERROR: Dependency "libavdevice" not found, tried pkgconfig

How

Add libavdevice-free-devel package.

Where

Fedora Linux 40, KDE Plasma.

Thank you for the PR.

Any reason why it is a draft?

Thank you for the PR.

Any reason why it is a draft?

Because i need to see if this PR is worth enough to merge.
If the code is good enough to merge, then please merge.
If the code is not good enough to merge, then it is easier to discuss and revise the code.

Could someone with Fedora confirm?

[Moxie07]

I had tested the issue in Fedora 40 docker image and Fedora 40 KDE virtual machine. The result is:

1. In Fedora 40 docker image, the build is successful without libavdevice-free-devel package installed.
2. In Fedora 40 KDE virtual machine, the build is not successful without libavdevice-free-devel.

Conclusion is, this is a Fedora KDE issue, not Fedora in general.
Maybe we can add it just in case?
