[git commit] loadfont: 32k size limit is not enough

[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=2b288236e80938d29324072a823f46861bd07cd3
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

Since our "read to malloced buf" routines only gradually grow
allocations, let's be generous here and allow 128k.
