When invoking /bin/sh, its default PATH is used. On some systems, that does
not include the PATH where the ipsec script is installed, as charon is invoked
with a custom PATH. Explicitly setting the PATH of charon should fix this
case, properly invoking the (default) updown script.
Fixes#745.
The child_updown() function sets up environment variables to the updown
script. Sometimes call to hydra->kernel_interface->get_interface() could
fail and iface variable could be left uninitialized. This patch fixes
this issue by passing "unknown" as interface name.

INCLUDES are now deprecated and throw warnings when using automake 1.13.
We now also differentiate AM_CPPFLAGS and AM_CFLAGS, where includes and
defines are passed to AM_CPPFLAGS only.
