[OE-core] [PATCH] selftest/archiver: invalidate stamps instead of removing TMPDIR

[leonardo.sandoval.gonzalez at linux.intel.com]

From: Leonardo Sandoval <leonardo.sandoval.gonzalez at linux.intel.com>

There is no need to remove the whole TMPDIR, instead just invalidate
stamps and build again the targets. Local runs demostrate the patch reduces
the execution time considerably (see below), indicating the extra work done
by rmtree. In the other hand, the following checks after archiver were affected
because they started from a clean TMPDIR.

Before:
2017-01-31 17:39:39 -   test_archiver_allows_to_filter_on_recipe_name (oeqa.selftest.archiver.Archiver) ... OK (468.928s)

After:
2017-01-31 18:00:08 -   test_archiver_allows_to_filter_on_recipe_name (oeqa.selftest.archiver.Archiver) ... OK (297.524s)
