keepassxc: enable fdosecrets by default
https://github.com/void-linux/void-packages/pull/28020

Description:
This allows one to use `keepassxc` as a secrets storage via `libsecret`.

Note that `kwallet` is currently unusable from `qtkeychain` except in kde (#26774), so I'm looking for an alternative.

I checked that the package compiles, installs, and runs with this option enabled.

After configuration, it works ok with `owncloudclient`. I followed this guide https://avaldes.co/2020/01/28/secret-service-keepassxc.html to setup.
