Revert "	- Remove a patch. Those are already undefined by default and log{in,out,wtmp} do not exist in libutil so the configure can't find them and thus they are not used in the build"

This reverts commit a2db696a27111b767d5b68d4efb8d8c6c279dd2f.
I think this is it...
	- Remove a patch. Those are already undefined by default and log{in,out,wtmp}
	  do not exist in libutil so the configure can't find them and thus they are not used in the build
	- Stop using pkg-install by now. Rename the file pkg-install.old (will be probably removed in the future)
	- Update pkg-plist
	- Update the Makefile a bit
Add a new patch, true doesn't live in /usr but in /usr/bin. Also add pkg-install.old, which does nothing but I want to keep that file around in the git repo as a guid for a while.
