Delay return from updateUbootEnvVars() until service file finishes
This commit, as the title might suggest, delays the return from the
function updateUbootEnvVars() until the called service file completes
running. The reason for this change is because the service file runs
asynchronously, so activation seemingly finishes before the priorities
are actually changed.
This is accomplished by adding a generic function waitForServiceFile()
which waits until the completion of a supplied one-shot service file or
until a timeout is reached.
Resolves openbmc/openbmc#2857
