[yocto] [yocto-autobuilder][PATCH] PublishArtifacts.py: fix file check to work under dash

[Bill Randle]

An earlier patch (ed3857990) to check for existing msd5sum files worked
fine when tested under bash, but failed with an error message about [[
not found when run under dash. Updated the test to not rely on bashisms.
