shared: add nm_utils_strv_find_first() helper

* nm_utils_strv_find_first:
* @list: the strv list to search
* @len: the length of the list, or a negative value if @list is %NULL terminated.
* @needle: the value to search for. The search is done using strcmp().
*
* Searches @list for @needle and returns the index of the first match (based
* on strcmp()).
*
* For convenience, @list has type 'char**' instead of 'const char **'.
*
* Returns: index of first occurrence or -1 if @needle is not found in @list.
