Export RBENV_ROOT before rbenv init for system-wide install

[jgarber]

I was having problems using rbenv with mina when it was installed system-wide (with fnichol's rbenv::system recipe).

I have set :rbenv_path, '/usr/local/rbenv' set in deploy.rb and an queue echo_cmd %{echo $PATH} before invoke :'bundle:install'.

       $ echo $PATH
       /home/vagrant/.rbenv/shims:/usr/local/rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
-----> Installing gem dependencies using Bundler
       $ mkdir -p "/srv/myapp/shared/bundle"
       $ mkdir -p "./vendor"
       $ ln -s "/srv/myapp/shared/bundle" "./vendor/bundle"
       $ bundle install --without development:test --path "./vendor/bundle" --binstubs bin/ --deployment
       bash: line 118: bundle: command not found
 !     ERROR: Deploy failed.

To get rbenv to work, I set queue %{export RBENV_ROOT=#{rbenv_path}} before invoke :'rbenv:load'. Then I get:

       $ echo $PATH
       /usr/local/rbenv/shims:/usr/local/rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
-----> Installing gem dependencies using Bundler
       $ mkdir -p "/srv/myapp/shared/bundle"
       $ mkdir -p "./vendor"
       $ ln -s "/srv/myapp/shared/bundle" "./vendor/bundle"
       $ bundle install --without development:test --path "./vendor/bundle" --binstubs bin/ --deployment
       Using rake (10.0.3) 
       ...

Awesome, thank you! This is exactly the same issue I was running into with my system-wide rbenv installation.

This was fixed by #117.
