oeqa/utils/decorators: LogResults fix race condition in linkfile
In order to avoid race condition when test if exists the linkfile use bb.utils.lock, the best solution is to create a unique name for the link file. There is no way to create a unique linkfile name at this decorator because is needed the machine and image variables, those variables can't be passed easily in this code. To avoid broke test export functionality use a try/except because bb isn't available when use test export [YOCTO #10225] Signed-off-by: Aníbal Limón <anibal.limon@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
