Draft: fix(macos): create-dmg dependency issues

The PR fixes the dependency issues for MacOS DMG builds.

• The fix has been only tested for the master branch
• The fix may break when dependencies are updated

The PR is a step towards fixing #9713 (closed)

TODO

• Add a flag for debug logs when running makebundle.py (helpful in debugging)
• Add conditional for x86_64 path of dependencies in gajim.spec file

How to verify

Start by building Gajim for MacOS:

./gajim-macos-helper.sh build

The build command clones a gajim-source.
And the create-dmg command uses the gajim-source/mac/gajim.spec file.

For testing the fix, cd into gajim-source and checkout to the fix branch:

cd gajim-source
git fetch https://dev.gajim.org/niyabits/gajim fix/macos-create-dmg:fix/macos-create-dmg
git checkout fix/macos-create-dmg

And then run:

./gajim-macos-helper.sh create-dmg
open gajim-source/gajim-2.4.1-41-g9cab92c1c.dmg
