app-admin/lastpass-binary-component: new package #571280

This is a split off from app-admin/lastpass and only installs the binary
component required by the browser extension, as opposed to installing
the extension too. Beginning with lastpass-4, the upstream only
installs the binary component.

Also, add this package as a blocker for app-admin/lastpass. These two
packages cannot be installed at the same time as that would introduce
file collisions.
