cros_workon: Return zero if no ebuilds were started/stopped.
The way it's currently written, ebuild_to_{live,stable} would return
a non-zero value if no ebuilds were converted, because bash functions
return the value of the last statement. Changing it into an if-statement
solves this problem.
BUG=brillo:634
TEST=cros_workon start/stop return zero if no package was changed.
