[aarch64-port-dev ] Sync AArch64 8u JDK Repository with upstream 8u72

[Andrew Hughes]

I did a comparison of the AArch64 jdk8u repository [0] with the
upstream jdk8u72-b15 tag and found a couple of differences that
could be resolved.

1. The change
"8131105: Header Template for nroff man pages *.1 files contains errors"
seems to have been reverted. Re-applying this fixes the issue.

2. Two solutions for a libpng on ARM issue [1] seem to have been applied.
Now that the upstream 8078245 version is present, we can revert the change
to the libpng sources, keeping them pristine and making it easier to apply
future upstream updates to them.

Ok to push?
