Bump skydive version to 0.28

Skydive versions prior to 0.28.0 panic on newer versions of libc.
Fixed upstream in 0.28, see: skydive-project/skydive#2329
This should be backported to at least xena and yoga, as skydive is
currently not working with centos 8 on these releases.

Closes-Bug: #1940862
Change-Id: I177949b9319a977c9cd9121eb28b710256b72a5a
(cherry picked from commit 1f1214d)
