NOTE: I'm not sure this is really the route I want to go here, but it
would need benchmarking to show if it's actually beneficial.
It would still be nicer to get something like this upstreamed instead.
trim down anything not used directly by tar-split.

I intend to not make changes to this `archive/tar` that aren't from
upstream, or are not directly related to the usage by this project...

This is a port of commits adding RawHeader() to go-1.11 archive/tar.
In addition:
* simplify the rawBytes.Write() code in readHeader()
* ignore errors from rawBytes.Write(), as (at least for go-1.11)
it never returns an error, only panics (if the buffer grew too large)
Also, remove the internal/testenv from tar_tar.go to enable go test.
As working symlink detection is non-trivial on Windows, just skip
the test on that platform.
In addition to `go test`, I did some minimal manual testing, and
it seems this code creates tar-data.json.gz which is identical
to the one made by the old version.

The issue was identified while
working with round trip FileInfo of the headers of hardlinks. Also,
additional test cases for hard link handling.
