[PATCH 7/8] Makefile: use $(wspfx) for $(QUIET...) in shared.mak

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Change the mostly move-only change in the preceding commit to use the
$(wspfx) variable for defining the QUIET padding, to guarantee that
it's consistent with the "TRACK_template" template.

    $ make CFLAGS=-I$RANDOM grep.o wspfx='$(space)->'
     -> GIT-CFLAGS PARAMETERS (changed)
     -> CC grep.o
