src: promote 'reject with icmp CODE' syntax

The kernel already assumes that that ICMP type to reject a packet is
destination-unreachable, hence the user specifies the *ICMP code*.

Simplify the syntax to:

	... reject with icmp port-unreachable

this removes the 'type' keyword before the ICMP code to reject the
packet with.

IIRC, the original intention is to leave room for future extensions that
allow to specify both the ICMP type and the ICMP code, this is however
not possible with the current inconsistent syntax.

Update manpages which also refer to ICMP type.

Adjust tests/py to the new syntax.

Fixes: 5fdd0b6a0600 ("nft: complete reject support")
