Update golang.org/x/sys to fix OSX compatibility

Signed-off-by: Ed Snible snible@us.ibm.com

Resolves #238

The fix is basically these three commands from the .bingo directory:

go get -modfile=jsonnet.mod -u golang.org/x/sys
go get -modfile=jsonnetfmt.mod -u golang.org/x/sys
go get -modfile=gojq.mod -u golang.org/x/sys

Note that this repo doesn't check in the .sum files. I am in the habit of checking them in for Go (see https://stackoverflow.com/questions/53837919/should-go-sum-file-be-checked-in-to-the-git-repository ), but I don't know Bingo conventions do I did not check them in here.

@esnible according to thanos-io/thanos#5392 (comment), you can add the .sum files that were updated to the PR.
