fix: add -c flags when building go test

[fl0Lec]

when building a go test without the -c flag like so:

 builds:
- command: test
  binary: env.test
  dir: ./internal/builders/golang
  no_main_check: true

will result in the error: exit status 1: fork/exec : exec format error

adding the -c flags when not present in the flags
adding unit test

#4462
