Merge c74c74eb0a9f2a11015a00ce1551a290797b11dc into 06413631029de32cd9af15b6b7f6ed77743cbd79

Let's say we have nvm installed in a separate mount, /.socket. NVM_DIR is $HOME/.nvm in /etc/profile.d/nvm.sh. With this setup, users can install Node versions to their home directories without each installing nvm.

nvm install --lts

This works fine as does nvm use --lts. When nvm exec is used though, it fails because it looks for nvm-exec in $NVM_DIR. First fix is to look for nvm-exec in $NVM_DIR. If NVM_DIR does not contain nvm-exec, check $BASH_SOURCE[0]. The second fix is to follow nvm-exec if a symbolic link to determine the proper location of nvm's home. Alternatively we could use a second environment variable, NVM_HOME in exec instead of relying on the directory name of nvm-exec.
