glyphs: fix types

Browse Source 
The code was written on top of buffers of `char[26]`, and then was
changed to use `char *`, yet was still using `sizeof buf`, which
became `sizeof (char *)` instead of `sizeof (char[26])`.

Reported by Dagobert Michelsen.

* src/glyphs.h, src/glyphs.c: Get rid of uses of `char *`, use only
glyph_buffer_t.
