pppd: fix build with 3.5+ kernel headers
Fixes http://autobuild.buildroot.net/results/8a9369fece696e012249b865708ffee533c5318a Pppd bundles some, but not all needed kernel headers. In Linux 3.5 (and before that 2.6.35) if_pppol2tp.h was changed, so the embedded copy was no longer compatible. if_pppol2tp.h has been part of the exported kernel headers since 2.6.23, so simply drop the bundled copy and use the kernel headers instead, similar to how it is done in Gentoo: https://bugs.gentoo.org/show_bug.cgi?id=427684 Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
