bg: deduplicate job argument

Browse Source 
"bg %1" of a pipline prints the same line twice because it tries
to background the same job twice.  This doesn't make sense and
other builtins like "disown" already deduplicate, so do the same.
Unfortunately we can't use the same approach as "disown" because we
can't hold on to references to job, since we're modifying the job list.
