stdlib: Fix resource downloader download to cwd upon failure
There are some cases where default downloading to `~/.cache/gem5` will
not work (for example, running gem5 in a Docker container, an error
observed here:
https://gem5-review.googlesource.com/c/public/gem5/+/51950).
To fix this, the `_get_default_resource_dir` has been altered to iterate
through a list of default resource directory targets. This change will
mean if `~/.cache/gem5` is not available then the resource is downloaded
to the current working directory of gem5.
