libnm-core: return NULL from _nm_utils_slist_to_strv for empty lists

Browse source 
The function is used, among others, in the get_property() of many
objects to return a boxed strv from a list. The default value for a
boxed strv property is NULL, but _nm_utils_slist_to_strv() returns a
pointer to an array with zero elements when the list is empty.

Change the function to return NULL if the input list is empty.
