libcaca: shrink 2nd arch packages to avoid duplicate files. (#575)

* Drop the mirror for SOURCE_URI, since the official website is back.
* No changes, other than SOURCE_URI, in primary arch base packages.
* On primary arch devel pacakges, move documentation/man/man3/ and
  develop/documentation/libcaca/ to a libcaca_doc arch-independent
  package, without any dependencies, though, for more flexibility.
* On secondary arch there is no need to ship man pages, data files
  and runtimes (except for caca-config-*), since they are already in
  the new doc package. All we need for secondary arch packages is:
    in the base package: the shared libs;
    in the devel package: caca-config-* and develop/{headers,lib}.
  The only file we need to keep in every package is the licence.
* Cosmetic: fix double white spaces, fake tab, add "-e" for sed.
* Add TEST() with "make check". Test results: PASS = TOTAL = 5.
