Show harvester version on console dashboard

* Add a new version variable `HarvesterVersion` to store version of
  harvester. Console dashboard shows this version, instead of the
  installer version.

* Add a new script `version-harvester` to determine and set up
  `HARVESTER_VERSION` variable for later use.

* Update script `version`: Unset variable `DIRTY` in case it was set
  somewhere else.

* Update script `build`:

  - Pull harvester source from github if not exists. This will happen if
    we're calling `make` from harvester-installer, but not from calling
    `make build-iso` from harvester.

  - Source "version-harvester" script to get the version of harvester.

  - Update both harvester and harvester-installer version variables
    using ldflags, `HarvesterVersion` and `Version` respectively.

Tested by calling `make` from harvester-installer and `make build-iso`
from harvester.
