Title: restore inclusion of specs_dir sub-directories

It looks like 5a37c3df38b7e3a759b0897e6c1774a7ed83f488 removed the `**`
from the pattern used to generate the specs array. This has the effect
of only running specs located directly in the `specs_dir` directory.

For example, with the following directory structure, only `foo_spec.rb`
would be run with an invocation of `rake spec`.

spec/foo_spec.rb
spec/bar/bar_spec.rb

This patch restores the `**` passed to `Dir.glob` and also uses
`Dir.join` for generation of the path to the spec helpers directory.
