Sort fuzz target dependencies to avoid rebuilds.

Some fuzz target dependencies are generated at Soong-time in a
nondeterministic fashion. When these are interpreted by Make, they may
cause rebuilds due to being in a different order.

Ensure that the dependencies are always sorted, which should avoid
triggering unnecessary rebuilds.

Bug: 144250431
Test: make <module> && make <module>, ensure no rebuild.
