[OE-core] [PATCH] ruby: some ptest fixes

[André Draszik]

From: André Draszik <andre.draszik at jci.com>

* the (new?) ruby expects some additional compiled libraries
  to run, so we need to copy them as part of ptest.
  Fixes errors like:
  # ruby ./runner.rb ./-ext-/vm/test_at_exit.rb
  Run options:

  # Running tests:

  [1/1] TestVM#test_at_exit = 0.06 s
    1) Failure:
  TestVM#test_at_exit [/usr/lib/ruby/ptest/test/-ext-/vm/test_at_exit.rb:7]:

  1. [1/2] Assertion for "stdout"
     | <["begin", "end"]> expected but was
     | <[]>.

  2. [2/2] Assertion for "stderr"
     | <[]> expected but was
     | <["-:1:in `require': cannot load such file -- -test-/vm/at_exit (LoadError)",
     |  "\tfrom -:1:in `<main>'"]>.

* the 'erb' test can't find the erb binary, as we're not
  running this from within the build directory
