[PATCH v4 06/13] go.bbclass: ptest cleanup and improvements

[Matt Madison <matt@madison.systems>]

* Don't enable verbose test output (-test.v)
  by default, as it generates too much noise
  for automated results parsing

* Override do_install_ptest_base in the bbclass,
  so recipes can provide their own modifications
  with do_install_ptest.

* Improve the generated run-ptest script to better
  handle large numbers of tests, and to generate
  'status: test name' output similar to Automake
  tests.

* Install all non-vendored 'testdata' directories
  from the source into the ptest package, as some
  packages share test data among multiple tests.
