Removing homebrew and nvm.sh (#3)

* Removing homebrew and nvm.sh

Removing the local usage of homebrew and sourcing nvm.sh as this is
outside of the scope of Terraform.

When using the module the environment should be setup to have nvm and
enable the use of it. This is enough to allow building in other
environments and build systems like Jenkins or Atlantis.

* Revert "Removing homebrew and nvm.sh"

This reverts commit 45a4f7a.

* Remove homebrew and trust nvm is available.

Removing homebrew as that is platform specific and trusting nvm is
available to set the nodejs version.

NVM is being used with the -s flag during initial install to ensure it
works on Alpine Linux which has to have custom nodejs versions compiled
due to the libc difference.

This is going to cause the module to take longer to run.
