MINOR: vars: Parse optional conditions passed to the set-var actions

This patch adds the parsing of the optional condition parameters that
can be passed to the set-var and set-var-fmt actions (http as well as
tcp). Those conditions will not be taken into account yet in the var_set
function so conditions passed as parameters will not have any effect.
Since actions do not benefit from the parameter preparsing that
converters have, parsing conditions needed to be done by hand.
