Install ergoCubEmotions application even with COMPILE_ergoCubEmotions off

[martinaxgloria]

As per title, I created this PR to refactor the ergoCubEmotions module to have the ergoCubEmotions xml application for the yarpmanager on ergocub-laptop. In this way, when robotology-superbuild is installed:

• on ergocub-head the COMPILE_ergoCubEmotions flag is ON, so the module is properly installed to be run on it
• on ergocub-laptop the flag is OFF, but the xml for the yarpmanager is still installed. In so doing, the module can be launched from the laptop (as per all the other applications) attaching to the ergocub-head node.

I tried this changes on my laptop. The first time, I installed ergocub-software with the flag OFF, I opened the yarpmanager and I tried to launch the module from the configuration file (which is installed now):

Since no images and videos are installed, nothing is shown.

Then I rebuilt the repo with the flag ON, I repeated the passages listed above and this time I was able to see the expressions:

I'll take this PR in draft until these changes are tested on the robot.

Since ergoCub was not available, I tested the changes on the ergoCub setup on bench with the Orin NX and they worked smoothly: with this PR the module could be launched via the yarpmanager launched from the laptop, as the other yarpmanager applications

So we go for the solution proposed by @Nicogene? I could modify the README.md in accordance to this change
