Subject: [PATCH] Improve aliBuild clean (#306)

- Now supports the --aggressive-cleanup option, which can be used
  to remove extra files which come handy only in case of rebuilds.
  This means that in general the cleanup has no side effects, but
  it will take longer to rebuild a package.
- Do not remove files which do not exists.
