Have the new dtrace-modules-provider-headers obsolete the old.

Have the new dtrace-modules-provider-headers obsolete the old.

The package name has changed but the new package contains the same files as the
old, so we need to Obsolete: the old ones so that yum will remove them.

(Because the old scheme generated package names on the fly according to the
running kernel, the list in this patch may well be missing a few packages.)

Caveat: this fixes 'yum update' but cannot fix direct RPM installation.
You'll have to uninstall the old package manually if you do that.
