exec()s an i3 utility, for example the config file migration script or i3-nagbar.
This function first searches $PATH for the given utility named, then falls back to the dirname() of the i3 executable path and then falls back to the dirname() of the target of /proc/self/exe (on linux).
This function should be called after fork()ing.
The first argument of the given argv vector will be overwritten with the executable name, so pass NULL.
If the utility cannot be found in any of these locations, it exits with return code 2.

This function resolves ~ in pathnames.
It may resolve wildcards in the first part of the path, but if no match or multiple matches are found, it just returns a copy of path as given.
