Do they both originate from frustration?
In spin liquids, the ordered state is broken by zero-point fluctuations even at $T=0$. Even though it is common for spin liquids to be frustrated, it is not necessarily so. The $S=1$ Heisenberg spin chain (AFM), for example, is a spin liquid without being frustrated.
The name spin liquid comes (I believe), from the exponentially decaying correlation (like in liquids).
Spin glass on the other hand is always frustrated. The easiest way of thinking about spin glass is by picturing an Ising model with random couplings $J_{ij}$. The actual ground state of such a system will be hard to determine, as there will be many metastable states. Again - just like in regular glass.
