geoclue2: update to 2.6.0 + enable it for redshift.
https://github.com/void-linux/void-packages/pull/35785

Description:
<!-- Uncomment relevant sections and delete options which are not applicable -->

#### Testing the changes
- I tested the changes in this PR: **YES**

imo the geoclue2 build option is useless because it's no hard dependency and redshift will work fine without it if you change the provider to "manual" in `redshift.conf`, but I'll leave it for now...
