gstreamer1.0-plugins-bad: Fix packageconfigs and patches

This reintroduces fixes and changes which were introduced in the original
gstreamer1.0-plugins-bad 1.8.1 upgrade commit.

* packageconfigs changed since GStreamer 1.6.3
  (they often do between minor version increases like 1.6 -> 1.8)
* hls,tinyalsa packageconfigs moved into the .inc file
* vulkan packageconfig dropped since there are no vulkan libraries in OE
  (libxcb alone is not enough)
* reintroduced glimagesink downrank patch (it was removed because it was
  dangling before)
* fixed patch line numbers

gstreamer1.0-plugins-bad: upgrade to version 1.8.1

0002-glplugin-glwindow-fix-memory-leak-of-navigation-thre.patch is a
backport, and is no longer needed.

configure-allow-to-disable-libssh2.patch got replaced by a patch that does
the same thing but has been submitted.

Vulkan is disabled for now since libxcb alone is not enough - the Vulkan
headers and libraries are needed as well.
