nvm does not work correctly on armv7l

[chenghung]

I need to patch nvm.sh

case "$NVM_UNAME" in
  *x86_64*) NVM_ARCH=x64 ;;
  *i*86*) NVM_ARCH=x86 ;;
  *armv6l*) NVM_ARCH=arm-pi ;;
  *armv7l*) NVM_ARCH=arm-pi ;;    # patched here
  *) NVM_ARCH="$(uname -m)" ;;
esac

You can do *armv61* | *armv71* if it's the same architecture.

Does that work equally well on all node and io.js versions? I'll happily accept a PR :-)

There are actually separate builds for armv6l and armv7l here in io.js v1.3.0 because they are different architectures.
