main/postmarketos-ui-plasma-mobile: add some new depends

This MR currently breaks pmbootstrap, as it doesn't handle $depends containing itself. This is however supported by abuild and used by several packages (and I've seen some do it in Adélie), so it should be supported anyway.

I've ordered the $depends list alphabetically for better readability, and added the bluedevil (for Bluetooth) kwallet-pam and xdg-desktop-portal-kde runtime dependencies.
