wayland/agl-compositor_git.bb: Bump SRCREV

This SRCREV bump update formally removes SMACK and Waltham
and modifies the client screenshooter client to generate
a PNG screenshot for each output -- rather than creating an
image for all outputs.

SRCREV bump:

- 69bd3ddac4b23 policy-deny: Remove SMACK support
- 0ed8064b0de23 compositor: Remove Waltham support
- e0a1dcc548087 clients/screenshooter: Add the output name to screenshot name
