utils: add nfct_destroy() to all examples in utils

This patch adds nfct_destroy() to all the examples in the utils folder.
Although this may be obvious to some, when I wrote my first code using
libnetfilter_conntract, I used the examples but subsequently missed out
all the calls to nfct_destroy().
