[rubygems/rubygems] Remove unnecessary nesting from standalone specs

Originally, all the specs in this file were put inside a shared examples
block, and since then all specs were run only changing the cwd (either
from root, or a subdirectory).

This was in https://github.com/rubygems/rubygems/commit/d7291700d016, to cover a fix in
the `bundler_path` method.

However, reverting that fix does not make any of the specs in either of
the main blocks fail! Only an unrelated spec of `bundle install
--standalone --local` fails.

The reason is that all specs set `path` to an absolute path, making the
fix essentially uncovered.

In order to simplify the file structure and improve runtime, I
completely removed the shared examples block, and only run main specs
for the root directory. Then I added a couple of extra specs to cover
the original bug fix.

This cuts runtime of this spec file in half, from 1m30s to 45s on my
laptop.
