Windows e2e runner reports awk failure

[brad-defined]

The Windows e2e runner reports the following error:

Run make e[2](https://github.com/DefinedNet/nebula/runs/5554733633?check_suite_focus=true#step:8:2)evv
  make e2evv
  shell: C:\Program Files\PowerShell\7\pwsh.EXE -command ". '{0}'"
  env:
    GOROOT: C:\hostedtoolcache\windows\go\1.17.7\x64

Looks to be an issue in the Makefile

# Set up OS specific bits
ifeq ($(OS),Windows_NT)
	#TODO: we should be able to ditch awk as well
	GOVERSION := $(shell go version | awk "{print substr($$3, 3)}")
	GOISMIN := $(shell IF "$(GOVERSION)" GEQ "$(GOMINVERSION)" ECHO 1)
	NEBULA_CMD_SUFFIX = .exe
	NULL_FILE = nul
else
	GOVERSION := $(shell go version | awk '{print substr($$3, 3)}')
	GOISMIN := $(shell expr "$(GOVERSION)" ">=" "$(GOMINVERSION)")
	NEBULA_CMD_SUFFIX =
	NULL_FILE = /dev/null
endif
