Note: I did not obsolete the sample subpackage now gone, presume someone wants to package it on its own.

- Update to version 2.11.0
+ Added: Intel® VPL API 2.11 support
+ Removed: Command line tools. They have been moved to a separate
repository (https://github.com/intel/libvpl-tools)
- Drop samples sub-package as the tools have been removed upstream
- Drop u_buildfix-i586.patch, no longer needed nor applies after
removal of tools
- Use ldconfig_scriptlets macro for post(un) handling.
