Restore 0.8.x behavior where java driver is marked as detected when
`java -version` exits with 0 but returns unexpected output.
Furthermore, we restore behavior when `java -version` where we parse the
first three lines of `java -version` but ignore rest.
If `java -version` returns less than 3 lines, Nomad 0.8.7 would panic.
In this implementation, we'd still mark java as detected but returns
empty version.
The 0.8.7 logic for detecting java version is found in
https://github.com/hashicorp/nomad/blob/v0.8.7/client/driver/java.go#L132-L172
.
I punt on revamping how we can be more resilient to java -version
syntax, and aimed for preserving existing behavior instead.

Due to https://github.com/tsenart/deadcode/issues/3 we can't specify
these consts on their own. This moves them into the _platform_test.go
files to avoid creating a package that only exposes a couple of values.
* Docker for Windows does not support ulimits
* Use filepath.ToSlash to test workdir
* Convert expected mount paths to system style
* Skip security-opt test on windows
- Windows does not support seccomp, and it's unclear which options are
available.
* Skip StartN due to lack of sigint
* docker: Use api to get image info on windows
* No bridge on windows
* Stop hardcoding /bin/
