[shell] Avoid side-effects during eval (#3459)
Take two.
* Avoid eval if the prefix contains `:=`
* This is not to evaluate variable assignment. e.g. ${FOO:=BAR}
* [zsh] Prevent `>(...)` form
* Suppress error message from prefix evaluation
* Stop completion when prefix evaluation failed
Thanks to @calestyo
