6b94f5ef51 reverse mode: -exclude: filter out excluded .name files 
Fixes https://github.com/rfjakob/gocryptfs/issues/286 :

While the actual file is properly excluded, the * .name file is still leaked in the directory listing:

a2f83acc30 tests: fix VerifyExistence() helper, it missed unstat()able files

cdb57ca7e0 fsck: Do not show files/directories without access permissions as corrupt. 
When running as a regular user, error EACCES does not necessarily mean that the
file/directory/xattr is corrupt, but just that we do not have sufficient access
permissions. Add a hint that running as root can be used to check everything.

When the old size is zero, there are no existing blocks to merge the
new data with. Directly use Ftruncate if the size is block-aligned.

772afa93f9 tests: add fd leak retry logic to UnmountErr, really return error 
Give the gocryptfs process one extra millisecond to close
files. Allows us to drop several other sleeps.

UnmountErr now really returns an error when it detects an fd leak
instead of just printing a message.
