recipe_sanity.bbclass: avoid error when running 'bitbake -e'
Running 'bitbake -e' without further arguments causes a stack trace on stderr:
| ERROR: Command execution failed: Traceback (most recent call last):

| if not fp in expectedpaths:
| # __note("Path %s in FILESPATH not in the expected paths %s" %

| return False
| return expected != unexpanded
| which triggered exception AttributeError: 'NoneType' object has no attribute 'split'
Removing the commented second line in can_delete_FILESPATH() hides the error.
