[PATCH v3 13/13] Add testing with merge-ort merge strategy

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

In preparation for switching from merge-recursive to merge-ort as the
default strategy, have the testsuite default to running with merge-ort.
Keep coverage of the recursive backend by having the linux-gcc job run
with it.
