src: evaluate: support prefix expression in statements
Currently nft dumps core when it encounters a prefix expression as
part of a statement, e.g.
iifname ens3 snat to 10.0.0.0/28
yields:
BUG: unknown expression type prefix
nft: netlink_linearize.c:688: netlink_gen_expr: Assertion `0' failed.
This assertion is correct -- we can't linearize a prefix because
kernel doesn't know what that is.
For LHS prefixes, they get converted to a binary 'and' such as
'10.0.0.0 & 255.255.255.240'. For RHS, we can do something similar
and convert them into a range.
snat to 10.0.0.0/28 will be converted into:
iifname "ens3" snat to 10.0.0.0-10.0.0.15
