[Addon] Check process type properly when loading addonapi

In checking the condition to handle the path for addonapi
when require('addonapi') is called, it needs to check the
process type to know which process calls the module.

However, there's improper condition for process type.
That makes it unable to use addonapi regardless of process type.

This changes the condition so it can use addonapi
when the process type is valid.
