efreet_icon: Fix wrong inherit selection

Summary:
The list of elem->paths is given with the actual icon at position 0 and
the bigger the index is the lower the icon in the inherit structure is.

Due to the for loop beginning at 0 walking to the end this
direction is flipped. So the last r is returned, which is the lowest
icon in the inherit structure.

This is fixed by returning if the first valid path is found.

@fix

Test Plan: run jesus or efm with a custom icon theme beore the wrong icons are taken, now the correct ones are taken
