cmd/dist: simplify work list functions

Browse Source 
There are no uses of addCmd, so delete it. The only use of bgDirCmd is
dirCmd, so inline it. Now the only function that interacts with the
work queue is registerTest and dist's "background commands" are used
exclusively in goTest.bgCommand and registerTest (which calls
goTest.bgCommand).

For #37486.
