Check out the msan instrumented libraries by default.

Now that we have conditional support in DEPS, and have a policy
of "download everything the main bots need" by default, we
can download the instrumented libraries using the stock
download script, and delete the custom script that uses GYP_DEFINES.

Checking out the libraries adds 360MB for the no_origins version
and 2161MB for the chained_origins version. You can skip the
downloads by setting `"checkout_instrumented_libraries": False`
in the custom_vars section of your .gclient file (or by passing 
`--custom-var=checkout_instrumented_libraries=False` when running
`gclient config`). Passing `checkout_configuration="small"` will
also skip the download, along with multiple other optional things.,
