Use DEPOT_PATH instead of HOME in cmdlineargs test

[vchuravy]

I was running test with a custom JULIA_DEPOT_PATH set and I noticed that the cmdlineargs test were failing.

julia/base/client.jl

Line 317 in b3eaa34

!isempty(DEPOT_PATH) && include_ifexists(Main, abspath(DEPOT_PATH[1], "config", "startup.jl"))

is not using HOME
as a default path but rather the user depot.

I'm not entirely clear what these tests are testing, but if this works then it seems better than artificially changing the home directory.

Still seeming some failure locally so I will investigate further:
