agl-compositor_git.bb: Bump SRCREV for fixes

This SRCREV bump includes a couple of fixes for avoid a hard-to-catch
race between the gPRC proxy client the shell client. The update
simplifies the whole "conversation" between gRPC client and the
compositor.

In more details the following changes have been added since the previous
update:

- e3f8379e48433d grpc-proxy: Add a prefix tag for debugging messages
- ae3ef78cb1a01b grpc-proxy: Re-work bound_ok/bound_fail events handling
- 071440ef54444c shell: Provide a better explanation for terminating the connection
