Upstream's 6771b19 ("keep smoke artifacts in the build directory") made
omasnap-smoke reject positional paths; the directory is now passed with
--output-dir. check() still passed it positionally, so every build of a
pin at or past that commit failed with "Unexpected positional argument;
use --output-dir <directory>."
Pass it as --output-dir and move the pin to 6771b19, the tip the branch
tracker has been trying to merge since October 4. The two have to land
together: the old pin does not know --output-dir.
