Fix --clean <atom> so that it considers all packages within a given slot when

it's deciding which packages to keep, rather than just considering the ones
matched by the given atom. Any packages not matching the given atom are protected
from being unmerged. Thanks to Mart Raudsepp <leio@g.o> for reporting.
