Wrap abuild's newapkbuild

Created by: ollieparanoid

Alpine's abuild provides a nice newapkbuild tool, for which you can specify the source, and it will generate a state-of-the-art APKBUILD file accordingly by analyzing it.

We could simply wrap it with something like:

pmbootstrap newapkbuild [--folder=main] [everything passed through]

The --folder parameter will not collide, as it only uses single letter parameters.

When called, it would do the following:

• install abuild in the native chroot
• run newapkbuild with all parameters
• create a new folder in aports/folder/pkgname (we can parse the pkgname from the resulting APKBUILD)
• copy the generated APKBUILD to that new folder
