Rebased the 3 patches x11_disable_makekeys.patch, nodolt.patch and
include_fix.patch; since the patches are also used by other recipes of lower
versions, I created a new directory libx11-1.3.4/ to hold the rebased
patches (the original patches are still kept unchanged);
Updated LICENSE and LIC_FILES_CHKSUM, and reset PR to "r0";
Removed "patch=1" in SRC_URI as by default a patch is applied;
