fix(packaging): rename spec back to headset-battery-indicator, add Obsoletes

- Rename python-headset-battery-indicator.spec -> headset-battery-indicator.spec
- Change Name: python-headset-battery-indicator -> headset-battery-indicator
- Add Obsoletes/Provides for python-headset-battery-indicator to allow
  seamless dnf upgrade from both 1.3.0 and any python- named installs
- Remove headset-battery-indicator.spec from .gitignore (was added for
  PyInstaller, conflicts with the RPM spec file)
