oe-selftest: restore gummiboot tests

These are the gummiboot tests recently removed from OE-Core, with the
following changes:

* Make them use MACHINE = "genericx86-64" instead of "nuc" and remove
  all usage of meta-intel

* Use DEPLOY_DIR instead of assuming build directory will be in the
  default path relative to COREBASE

* Fix build test to actually check if the file was created as part of
  the test instead of possibly being around from a previous build

* Fix wic test to actually check the output to find the name of the
  .direct file that wic has created, instead of passing if any .direct
  file happens to exist in /var/tmp/wic

(We can now add these in this layer courtesy of Chris Larson's OE-Core
commit 182b8ed9f26ed8b6a8eb6dcaec82db9aca14b010).
