makefile: variables in make issue are now sorted

also, "\n get_variables" are removed from ISSEU_VARIABLES_NAMES.

These two superfluous words were there previously, don't know why or
how, but not easily spotted in an unsorted list.

I ran the command below to test before/after + we have CI tests for
make issue:

make print-ISSUE_VARIABLES_NAMES
