build: avoid warnings about unnecessary use of "return"

* src/grep.c (Gcompile, Ecompile, Acompile): Do not "return X"
from a function returning void, not even when X itself is a
function returning void.  This avoids warnings from Sun Studio 11
reported by Dagobert Michelsen.
* src/egrep.c (Ecompile): Likewise.
