[PATCH 1/3] scanner: replace binary characters '&' '|' and '!' by their names

[Pablo Neira Ayuso <pablo@netfilter.org>]

These symbol need to be escaped in bash and can lead to confusion,
so let's use their names instead which are still short, eg.

 nft add rule filter output meta mark and 0x3 == 0x1
