Runtime panic when running docker-mirror built with Go 1.17 on macOS

[dwickr]

After building with go build using Go 1.17 on macOS, docker-mirror panics:

$ go version
go version go1.17.3 darwin/amd64
$ go build
$ ./docker-mirror --help
fatal error: unexpected signal during runtime execution
[signal SIGSEGV: segmentation violation code=0x1 addr=0xb01dfacedebac1e pc=0x7fff20412c9e]

I can include more of the traceback if you want but it doesn't seem super useful.

Seems like updating the x/sys package will address this issue. From golang/go#46763
