makefiles: rename common.mk to prog.mk

For clarity, as it is included by the Makefiles that create programs and
non-shared-objects, but not by the ones that create shared objects (see
src/so.mk).

Commands used to move and search and replace:

    $ git mv src/common.mk src/prog.mk
    $ git grep -IFlz 'common.mk' -- src | xargs -0 -I '{}' sh -c \
      "printf '%s\n' \"\$(sed 's/common.mk/prog.mk/' '{}')\" >'{}'"
