profiles: keepassxc: add new socket location

The KeePassXC browser extension looks for the KeePassXC socket at
`${RUNUSER}/app/org.keepassxc.KeePassXC`[1].

But `${RUNUSER}/app` seems to be blacklisted in disable-common.inc under the
flatpak section[2], so the KeePassXC extension cannot connect to it.

Fixes #5447.
