When cleaning DBs, only look at directories

FS#9609 brought up an interesting issue where a user was prompted to remove
db.lck when running a -Sc operation concurrently with an -Syu operation
during a long download. Although there are other problems here, this fixes
the issue where files other than directories could be considered to be
databases. Fix this.
