oe-depends-dot: improve '-w' behavior

Browse Source 
The '-w' option is not giving very helpful information. For example,
if we add 'spice' to IMAGE_INSTALL, bitbake -g core-image-minimal,
and then run `oe-depends-dot -k nspr -w task-depends.dot', the result is:

  $ oe-depends-dot -k nspr -w task-depends.dot
  Because: core-image-minimal nss
  core-image-minimal -> nss -> nspr

The result is not showing the full dependency chain which brings in nspr.
With this patch, the result is:

  $ oe-depends-dot -k nspr -w task-depends.dot
  Because: core-image-minimal nss libcacard spice
  core-image-minimal -> spice -> libcacard -> nss -> nspr

This patch also fixes a typo in help message: recipe-depends.dot -> task-depends.dot.
