extensions: string: Adjust description of --to to recent kernel changes

This reverts commit 920ece2b392fb83bd26416e0e6f8f6a847aacbaa.

Since kernel commit c4eee56e14fe ("net: skb_find_text: Ignore patterns
extending past 'to'"), pattern scanning no longer happens past --to
offset even if skb_seq_read() returned a larger block. Point this out in
the description and also drop the '-1' offset which is not true as
kernel's selftest in tools/testing/selftests/netfilter/xt_string.sh
shows.
