Documentation: Go 1.7 is no longer suitable for building CI

[de-nordic]

Regarding "Command line tool" paragraph;

Due to changes applied with
apache/mynewt-newt@6a51e35, which is usage of ProcessState.ExitCode(), in newt/util.go, the minimal requirement for go compiler is now version 1.11.1.

I think it already required a minimum version of 1.12 because of this: apache/mynewt-newt@53f9e0c

[utzig]

@de-nordic Ah, you can probably disregard my comment, mynewt-mcumgr-cli depends only on newt/util so the version you mentioned seems correct.

[de-nordic]

Might be, I have built go from the top of master at that point (27fc32ff01) for the purpose of building the tool, so I have been far beyond 1.11.1 anyway during build; I have tracked missing feature to be included within go 11.1.1, since the version mentioned.

Seems at least 1.12 is needed becasue of os.ProcessState getting:

src/mynewt.apache.org/newt/util/util.go:498:10: state.ExitCode undefined (type *os.ProcessState has no field or method ExitCode)

With 1.11.6

The README.md still mentions:

The command line tool requires Go 1.7 or later.

Is this the only place where this information is out-of-date?
