zev: create and symlink events now inlude checksum

When a symlink or another new file is created, the resulting
zev events now include a signature for the new file.

Symlinks are treated like files that contain the "link" part
as text. Block and character devices have a signature based
on the format string "%c%d,%d", with 'b'/'c', getmajor() and
getminor() as values. All other file types will result in an
all-zero signature.

Hardlinks create a new directory entry, but no new inode.
Therefore, rdlink events still do not contain a signature.
