[PATCH 4/6] Makefile: add check target using fontlint

[Jan Pokorny]

Fontlint is a font checker accompanying FontForge.
The check will proceed the SFD files through it, outputting the messages
to both standard output and to the per commit specific file (failback
to per date specific if git information not available) for easy
regression checking.  This final part of "check" workflow can be done,
e.g., manually (with diff selecting the right files to compare).

To prevent logs from check messing the repo, capture them in local
.gitignore file that initially includes also archives and directory
with generated TTF files.
