[PATCH] configuregateway: Only match "function" in subshell

[Adrian Schmutzler]

When running OpenWrt master, "type <functionname>" only returns
"<functionname> is a function". Thus, to make the implementation
future-proof and since it is also working with the current state,
change the grep in execute_subshell to match "function".
