libayatana-common: Enable Lomiri features

[OPNA2608]

Description of changes

Working towards #99090.

Enable Lomiri features in libayatana-common. This will make even vanilla Ayatana indicators depend on LUD whose GUI tool depends on LUITK, which is not great for closure size: 61.4M -> 847.9M. We can introduce a lib output to LUD with only the library, which would solve this and bring it down to 61.5M, but I haven't tested if I moved everything correctly with that change or if something might break somewhere - I needed to moveToOutput afew things out of lib.

I plan to revisit this once Lomiri is far enough to build & launch into the DE on master, at which point testing the fallout of that should be easier for me. With nothing outside of Lomiri currently using libayatana-common anyway, this shouldn't be a problem for now. I've taken note of this in the Lomiri tracking issue.

nixpkgs-reviews were deleted but ACK that libayatana-common -> lomiri.lomiri-url-dispatcher -> lomiri.lomiri-app-launch -> lomiri.lomiri-api is failing due to missing includes, needs https://gitlab.com/ubports/development/core/lomiri-api/-/commit/029b42a9b4d5467951595dff8bc536eb5a9e3ef7 (sigh).

I found that it was a network proxy problem that caused the dependency download to fail, so I deleted the previous nixpkgs-review.

Hmm, well I reran nixpkgs-review locally, and it complained when building lomiri.lomiri-api:

In file included from /build/source/include/lomiri/util/GlibMemory.h:28,
                 from /build/source/test/gtest/lomiri/util/GlibMemory/GlibMemory_test.cpp:19:

So you can save yourself a nixpkgs-review, the PR is borked as-is until lomiri.lomiri-api is fixed. 😅

Builds fine again.
