[PATCH 08/12] Fix ematch cmp and nbyte syntax help text.

[Andreas Henriksson <andreas@fatal.se>]

From: Lionel Elie Mamane <lionel@mamane.lu>

The help/usage screen of ematch cmp and nbyte say recognised symbolic
values for "layer FOO" are link, header and next-header, but the code
does _not_ implement that: it will recognise "next-header" as what is
supposed to be "header" and will not recognise "header". The right
symbolic values seem to be link, network, transport. Here is a patch
that changes the help/usage screen to match the code.
