./redstack kick-start <image_type> does not returns error for invalid image types

if we use the partial name of valid image types (for eg. red of redis) then command does not gives error.

Since https://github.com/openstack/trove-integration/blob/master/scripts/functions_qemu#L52 uses expr because of which the problem crops up.

So a different way instead of expr should be used.

    Corrects condition to check valid SERVICE_TYPE

    Reasons:
    - Currently expr is used to match condition, because of which the if
      part of valid SERVICE_TYPE is used, for eg. "mysq" of "mysql", then
      it is not called as invalid SERVICE_TYPE.

    Changes:
    - Updates the condition to match SERVICE_TYPE in VALID_SERVICES.
