src: add datatype->describe()
As an alternative to print the datatype values when no symbol table is
available. Use it to print protocols available via getprotobynumber()
which actually refers to /etc/protocols.
Not very efficient, getprotobynumber() causes a series of open()/close()
calls on /etc/protocols, but this is called from a non-critical path.
Closes: https://bugzilla.netfilter.org/show_bug.cgi?id=1503
