Fix ifquery json output for --running and other options

Ticket: CM-7635
Reviewed By: CCR-3575
Testing Done: Tested failing ifquery output in json format

This patch fixes a bug introduced by 0dea0cfeeec8b342ee2e2b767daa4071ac760f31
("Add support to display status (pass, fail) in ifquery --check json
output").

This patch separates the json encoders for iface objects with and
without status (ifaceJsonEncoder and ifaceJsonEncoderWithStatus) so
that they dont interfere with each other.
