Mtime cache is desinged with assumption that files are not
removed. Unfortunately it's not always the case for memory-resident
bitbake as build/tmp can be removed to perform build from scratch.
In this case bitbake crashes when trying to create timestamps if
tmp/stamps/ hierarchy doesn't exist.
Simple check of file existance should solve this issue.
