Restore original (upstream) distfile URL. During initial `make makesum'
the distfile got fetched from the nearby Gentoo mirror but I didn't pay
enough attention and didn't notice that:
$ curl -sI https://mirror.yandex.ru/gentoo-distfiles/distfiles/libsixel-1.8.6.tar.gz | egrep HTTP\|Content-Length: HTTP/1.1 200 OK Content-Length: 4791628
Because both its size (previous distfile was 4778776 bytes) and contents
looked legit, I did not verify that it is identical to the file fetched
from GitHub directly. Comparing their contents show only some missing
files and directories (example programs and sample image files, none of
them are built or installed anyway); the source code itself is identical
between the two, as well as resulting `include/sixel.h' file which now
comes pre-generated:

Drop the LICENSE and README.md (which is basically the project's GitHub
front page) and install more commonly seen in packages ChangeLog and
NEWS files instead; while here, trim some excessive vertical whitespace.
