Subject: [PATCH] exec.go: do not write linker flags into buildids

The flags can contain build-specific paths, breaking reproducibility.

To make this acceptable to upstream, we probably need to trim the flags,
removing those known to be buildhost-specific.

Upstream-Status: Inappropriate [needs upstream discussion]
