cmd/go: omit build metadata that may contain system paths when -trimpath is set CGO flag variables often include system paths for header files and compiled libraries. The point of -trimpath is to avoid dependending on system paths, so stamping these variables is counterproductive. Moreover, the point of stamping build information is to improve reproducibility. Since we don't also stamp the versions of C compilers, headers, and libraries used in a cgo build, only the most trivial cgo programs can be faithfully reproduced from the stamped information. Likewise, the -ldflags flag may include system-specific paths, particularly if external linking is in use. For now, we omit -ldflags entirely; however, in the future we may instead want to parse and redact the individual flags. Fixes #52372.
