shared: remove unused nm_utils_str_simpletokens_extract_next()

This can be replaced by nm_utils_escaped_tokens_split().

Note that nm_utils_escaped_tokens_split() does not behave exactly
the same. For example, nm_utils_str_simpletokens_extract_next() would
remove all backslashes and leave only the following character.
nm_utils_escaped_tokens_split() instead only strips backslashes
that preceed a delimiter, whitespace or another backslash.

But we should have one preferred way of tokenizing, and I find this
preferable, because it allows for most backslashes to appear verbatim.
