qpep does not build

[gabeblack]

With go version 1.13:

 cannot find package "golang.org/x/net/context" in any of:
        /usr/local/go/src/golang.org/x/net/context (from $GOROOT)

...

Searching found that in latest go, you now just import "context". So changed the source files to do that, but now getting:

cannot find package "golang.org/x/sys/unix" in any of:
/usr/local/go/src/golang.org/x/sys/unix (from $GOROOT)

not sure the fix for that one, but looks like qpep doesn't build as is.
