xtables: fix missing ipt_entry for MASQUERADE target
The MASQUERADE target relies on the ipt_entry information that is
set in ->post_parse, which is too late.
Add a new hook called ->pre_parse, that sets the protocol
information accordingly.
Thus:
xtables -4 -A POSTROUTING -t nat -p tcp \
-j MASQUERADE --to-ports 1024
works again.
