cmd/go: skip updateBuildID on binaries we will run
On modern Unix systems it is basically impossible for a multithreaded
program to open a binary for write, close it, and then fork+exec that
same binary. So don't write the binary if we're going to fork+exec it.
This fixes the ETXTBSY flakes.
Fixes #22220.
See also #22315.
