[bash] Don’t print function definition when checking for existence (#3448)
When just checking whether a function is already defined or not, it’s not
necessary to print out it’s definition (should it be defined).

bash’s `declare` provides the `-F`-option (which implies `-f`), which should
give a minor performance improvement
