[PATCH weston 2/2] libweston: fix output reflow on removal

[Pekka Paalanen]

From: Pekka Paalanen <pekka.paalanen at collabora.co.uk>

This is regression apparently introduced in
0de859ede4bad72b5d3b78e086632f02196d997f, which accidentally swapped the
sign of 'delta_width' in the original call site. If one removes an
output, the remaining outputs on the right are getting moved even
further to the right.

The outputs to the right should be moved to the left instead, to close
the gap left by the removed output.
