Title: only add redis extension to travis build if pecl available

HHVM doesn't have PECL available and can't build the Redis extension, although it should have a PHPRedis implementation inbuilt. So making the build of the Redis extension for Travis dependent on PECL being available, mainly to stop HHVM builds failing unnecessarily on that hurdle.
