    Disable compaction daemon on eunit run couch startups
    
    Commit 21f9544 enabled the compaction daemon by default. And commit
    3afe3ad disabled the compaction daemon at the start of the compaction
    daemon tests. Unfortunately, the compaction daemon remains active
    during all the other EUnit tests.
    
    I attempted to override the [compactions] _default line in the file
    rel/files/eunit.ini but specifying `_default=` or `_default=[]` did not
    provide the desired behaviour.
    
    This change disables the _default config as part of
    `test_util:start_couch` after startup. This means there is a very
    brief period during which the daemon is running, but in empirical
    testing the only thing I've seen it manage to do is compact `_dbs`
    before being disabled.
    
    Tested with `make soak-eunit` for 3 hours; this seems to eliminate
    the `all_dbs_active` error we've been seeing in CI runs since the
    compaction daemon was enabled by default.
