literki: initial packaging.

literki: initial packaging.

No formal release yet, although upstreams ships an ipk with a version and
a packaging revision, so we pull from git.

Patches:
- Makefile was completely broken and had no install target,
  rewrites most of it.
- author has put a "switcher" feature in it, which is non-functional,
  disable it in conffile
- in the area in which the "slide" to bringup the keyboard starts, drags
  are not propagated to window below; make the area smaller so we can
  unlock the screen
