makefile: drop usage of --install
makefile: drop usage of --install

The "go build -i" invocation may slightly help with incremental
recompilation, but it will cause builds to fail if $GOROOT is not
writeable by the current user. While this does appear to work sometimes,
it's a concern for external build systems where "-i" causes build errors
for no real gain.

Given the size of the runc project, --install is not really giving us
much anyway.
