strongswan: swanctl: make send_cert local

When support for send_cert was added in 4b9453b9a4, the $send_cert
variable was inadvertently global.  Make it local to avoid polluting the
global namespace and make the code easier to reason about.

Fixes: 4b9453b9a4c8 ("strongswan: Add support for send_cert option")
