Bug#1795: Paths inconsistent in kernel and pppd

[Nils Rennebarth <nils@nus.pan-net.de>]

Package: ppp, source

The updated kernel source gets the ppp specific header from
/usr/include/linux, e.g:
  <linux/ppp-comp.h>

The ppp source package expects these to live in /usr/include/net

So pppd can't be recompiled from the source.
What is the right location?

(And as an aside, the copyright still mentions ppp-2.1.2b as source
instead of ppp-2.2)
