Update tracker to 1.10.2

[Jeremy Bícha]

Impact
=====
This update includes the new bugfix releases 1.10.1 and 1.10.2
https://git.gnome.org/browse/tracker/tree/NEWS?h=tracker-1.10
https://git.gnome.org/browse/tracker/log?h=tracker-1.10

The major change is that the tracker extractor is now confined by libseccomp for better security (LP: #1648921)

Test Case
=========
I recommend testing with Ubuntu GNOME 16.10 since it includes tracker.
1. After installing the update, log out and log back in just to make sure you're running the updated tracker
2. Download some pictures or music files to an indexed folder (~/Downloads, ~/Music, ~/Pictures are good)
3. Wait a few moments and see if the files show up in the GNOME Music app, the GNOME Photos app, and/or the GNOME Shell Activities Overview when searching for that filename.
4. You can also look for any tracker errors to show up in the GNOME Logs app (gnome-logs is a frontend to the systemd journal)

Regression Potential
====================
Low. Ensure that tracker still works.

We'll need to update this to 1.10.3 which whitelists a few more system calls.

[Jeremy Bícha (jbicha)]

For anyone following along, I'm waiting on a 1.10.4 since 1.10.3 didn't fully fix the regressions.

See https://bugzilla.gnome.org/776117

There was a 1.10.4 but there are still regressions caused by the new sandbox.

Making as wontfix since we aren't taking the new sandbox as an SRU. See my comment on LP: #1648921
