20-console-autosize.sh: use full path to font file

setfont 2.6.3 removed '.' from the font search path. Fonts were loaded
by name and not file name, breaking the hook on distributions with
a recent kbd package.

Loading fonts by filename at an absolute path was tested on:

* Void (setfont 2.6.3)
* Arch (setfont 2.6.3)
* Debian (setfont 2.5.1)
* Ubuntu (setfont 2.3.0)
* Alpine (busybox setfont)
* Chimera (setfont 2.6.3)

Fixes: #552
Closes: #553
