linknx: forcilbly disable smtp support

linknx has support for SMTP via libesmtp, however there's no clean way
to specify where libesmtp-config lives.
So when libesmtp is built it finds it via the headers and is
automatically enabled, but it fails to get the appropiate link line from
libesmtp-config because it's not found.
Fix it by forcibly disabling it. If someone is interested in working
with upstream about this an option like --with-libcurl should be
implemented in configure.

foomatic-filters: make location of enscript very clear

Passing --with-file-converter=enscript isn't enough since the build
system will try the fallback options (a2ps, mpage, texttops) if it's not
found.
This has two bad effects: one of the tools leaking from the distribution
making foomatic-filters think everything will be the same on the target
(and failing when that's not the case), and failed builds when none is
found (enscript is installed in the target directory, the build system
doesn't look there).
So just avoid the test by stating explicitly where enscript will live in
the target. Fixes:

openvpn: adjust iproute2 path logic

As reported in bug #6164 when using busybox iproute2 openvpn can fail to
locate the 'ip' utility.
This was correct until busybox 1.21.0 was released since it changed the
location of /bin/ip to /sbin/ip (what iproute2 proper does).
So adjust the ip path accordingly.
