[yocto] [yocto-autobuilder][PATCH v2] PublishArtifacts.py: fix filecheck to work under dash (or other POSIX shell)

[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.

V2: use POSIX shell expansion for simplified test (thanks Joshua)
