wpcarro.roam.googlers.com -> wpcarro

Until I change my hostname, I'll need to use wpcarro. Internally on
Google networks, this laptop is resolvable via wpcarro.roam.*

Idea: consider defining in ~/.profile:

DESKTOP_NAME=<name>
LAPTOP_NAME=<name>
CLOUDTOP_NAME=<name>

...and then refer to these environment variables throughout my
configuration that depends on them. E.g. -

  - configs/install
  - configs/uninstall
  - .zshrc
  - .ssh/config

For now, I'll stick with the path of least resistance.
