fate: fix acodec/vsynth tests for make 3.81

GNU make 3.81 applies pattern rules in declaration order rather than
by stem length as in 3.82.  This moves the more generic patterns above
the more specific ones such that they work with either make version.
Some of the vsynth patterns are also simplified a little.
