main/postmarketos-ui-xfce4: remove xfce4-battery-plugin and icon link
The xfce4-battery-plugin
doesn't need to be installed anymore since we switched to the "power manager plugin" in postmarketos-ui-xfce4 0.5.0 (MR !2722 (merged)).
The link to the old PostmarketOS icon isn't needed anymore for new installations. It was added due to issue #1418 (closed).
However, for some existing installations removing the link causes the disappearance of the pmOS icon on the menu button. Users have to set it manually back to /usr/share/pixmaps/postmarketos-logo.svg
. This is because the accoding config file gets copied into the users ~/.config folder and therefore doesn't get updated. Installations that are affected:
- Edge installations prior to 10th Feb 2022, icon is expected to get lost after upgrading
postmarketos-ui-xfce4
package. - Stable installations created as v21.12 or older, icon is expected to get lost when upgrading to future v22.12.
