Initial commit

With the 19.3.0 release, GraalVM supports two Java versions: Java 8 and
Java 11. This also affects all sibling packages, including GraalPython,
so the former graalpython-bin package is split in two:
graalpython-jdk8-bin (this package) and graalpython-jdk11-bin. We use
this opportunity to make several other adjustments as well.

We no longer provide a version of the package name without the “-bin”
suffix. It doesn’t seem likely that a built-from-source version will be
added to the AUR soon, and other packages like jdk8-openj9-bin or
jdk8-j9-bin don’t provide non-bin versions either.

To make it possible to install graalpython-jdk8-bin and
graalpython-jdk11-bin in parallel, the symlink in /usr/bin is removed
(as it would otherwise conflict between the two packages). Users can add
/usr/lib/jvm/default/bin/ or a similar directory to their $PATH, or
otherwise ensure that they can still run the right graalpython without
specifying its full path.

And finally, a .gitignore file never hurts.
