Downgrade Apache httpclient to 4.5.2.v20170210-0925

Eclipse platform uses this version from the Oxygen Orbit release for
Photon. In order to avoid that we end up with two slightly different
versions in the same p2 repository of the simultaneous release we
downgrade temporarily from the version 4.5.2.v20180410-1551 in the
Photon Orbit release.
