maint.mk: do not always evaluate intprops-related shell
* top/maint.mk (_intprops_names): Change := to just "=" to avoid using gnulib_dir undefined (gnulib_dir is defined later in the file, which will be fixed separately), and besides, there is no need to incur the cost of this shell invocation for every single use of this .mk file. Reported by Eric Blake in https://lists.gnu.org/archive/html/bug-gnulib/2016-12/msg00137.html
