* Extend XCADDY_GO_BUILD_FLAGS usage (#102)
Commit 47f9ded5d8 is not sufficient alone to
ensure that all go modules are installed with write bit set because 'go mod'
or 'go get' might install modules as read-only, too.
If set, the environment variable is appended for the other go commands that
support build flags.
* Make running 'go' implicit for build environment
The method newCommand runs only go commands so let's make command 'go'
implicit and rename it to make it more verbose.
Add environment variable
XCADDY_GO_BUILD_FLAGS
to override default build arguments from environment (#102).
To support flags with variable arguments Unix-style quoting is supported.
* fix: do not use only hardcoded "go"
* fixed comments and added env to readme
* move GetGo to an internal package
