Since 'build/siggen: Rework stamps functions'[1] the stamps directory
for each recipe is only created if there are stamps to be written. Some
recipes - such as package-index - only have nostamp tasks so the stamps
directory is never created, resulting in the rm_work task trying to cd
into a directory that doesn't exist.
Resolve this by simply checking the stamps directory exists before
trying to delete files in it.
