cicd: always run package jobs on branches and MRs

Imagine there is a bug report, you attempt to fix in MR. You want a new appimage with this MR's patch so that whoever reported the bug can test if it is fixed properly.

Currently package jobs are hardcoded to master and tags. These are ok defaults, just turn these jobs into manual jobs for everything else.

Package jobs will always run by default to ensure that related issues remain in their respective MRs without propagating to/affecting master.
