oeqa/selftest/devtool: abort if a local workspace already exist

if user run devtool selftests with a local workspacelayer
the tests fail with various error such as:

- devtool.DevtoolAddTests.test_devtool_add just hangs
- devtool.DevtoolModifyTests.* fail with the following error:

 ERROR: Found duplicated BBFILE_COLLECTIONS 'workspacelayer', check bblayers.conf or layer.conf to fix it.
 Found duplicated BBFILE_COLLECTIONS 'workspacelayer', check bblayers.conf or layer.conf to fix it.

Check if a workspacelayer exists, warn the user and abort the tests
