testing/terminus-font: Install acm and uni fonts
Those fonts can be used with busyboxs setfont utility theoretically.
Of cause they can also be used with kbds setfont utility. Either way
I believe they are useful and should be installed.
Furthermore, I moved the psf, acm and uni fonts to /lib/kbd because
that is the path where kbd-misc stores them as well.
