Paul Menzel 12a3fbdb7e libpayload: Use a static copy of font_glyph_filled()
libpayload needs a static copy of the out of line function
`font_glyph_filled()` in every TU that needs it. So make it static
inline.

This fixes a build error by gcc (Debian 7.1.0-12) 7.1.0 from Debian
Sid/unstable. This happens with any libpayload based payload like
coreinfo, nvramcui or tint.

```

/src/coreboot/payloads/libpayload/drivers/video/corebootfb.c:173: undefined reference to `font_glyph_filled'
