bcp38: Allow class-e through bcp38

It is increasingly likely 240/4 and 0/8 netblocks will be allocated as
unicast globally rout-able and reachable address space
240/4 is already enabled throughout linux and openwrt.

Permit these address blocks under bcp38 address validation, ie. remove
those ranges from the block list:

list match '0.0.0.0/8'       # RFC 1700
list match '240.0.0.0/4'     # RFC 5745
