defaultenv-2: remove global.tftp.path

This variable is set in /env/init/general and then used
in /env/boot/* which is a bit confusing. Also it does not
necessarily have to be a tftp path (could be nfs aswell).
Use a local variable in the scripts using it instead to make
the meaning a bit more clear.
