atom lib: couple of fixes for prev commit
15{5,6}* tasks: profile/**/package.mask to profile/**/*[1]

Instead of getting only ghost ebuilds from package.mask files we
use new method from profiles lib that returns all possible files
(<- its a [1]), parse them and store results in tmp table

Due to this change we also renamed our tasks
157_profile_masks: rename, deps fix
161_profile_masks; rename and deps fix
