various/openjdk[9,10,11,12]: Remove 32 Bit patches and fix build for make 4.3

This MR cleans up my current OpenJDK-ports:

• Remove 32 bit patches as oracle dropped support (and they aren't compiled anyways)
• Add patch for make 4.3 compatibility
• Fix for the sched_getaffinity issue (see #11322 (closed))
• Use github for downloading source (faster than hg from openjdk)
• Format APKBUILD files and make them more similar between openjdk-versions
• Replace old bugs.a.o URL with current gitlab.a.o
• Remove dbg package as no one really needs that (and it's insane large)
