Replace rebar_util:get_cwd/0 by rebar_utils:get_cwd/0.  Luckily the
misspelt module name doesn't seem to have caused any harm, since
rebar_app_utils:is_app_dir/0 and rebar_rel_utils:is_rel_dir/0 aren't
called (only their /1 counterparts).

Change from lists:is_member/2 to lists:member/2, since the former
doesn't exist (the bug only affects rebar_plugins).

*If* there is a deps_dir tuple in the root rebar.config then
that is used globally as the deps dir. This is to stop dependencies for dependencies being
created in a different deps_dir even if the sub dependency so specifies.

Modules that include the EUnit header get an implicit test/0 fun,
which cover considers a runnable line, but eunit:(TestRepresentation)
never calls.  Result: prod modules with tests can never reach 100%
coverage.  Ironic.  In this case, fix it by decrementing the NotCovered
counter returned by cover:analyze/3.
