bitbake: lib/bb/utils: fix error in edit_metadata() when deleting first line

Browse Source 
If you tried to delete the variable on the first line passed to
edit_metadata() this failed because the logic for trimming extra blank
lines didn't expect the list to be empty at that point - fix that bad
assumption.
