bipedal-locomotion-framework: Add missing dependency on UnicyclePlanner

[traversaro]

While debugging #907, I noticed that the dependency on UnicyclePlanner was missing from bipedal-locomotion-framework. Even if this does not fix #907, it is an issue worth fixing.

Unfortunatly, this will take ~1.15 hours. One reason to go forward with #752 and move yarp to be packaged directly in conda-forge (this would also give us the advantage of having yarp packages on arm64 on Linux and macOS).

The Linux build was successful!
