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.
