features/trash: Handle unexpected errors during mkdir

When expected directory hierarchy in not present in trash directory,
trash translator tries to create it inside the same. Any errors from
posix other than the expected ones should be handled properly during
an internal mkdir call and logged accordingly explaining the reason
for not moving the file to trash directory.
