cmd/go: allow symlinks of non-directory files in embed
We previously disallowed all non-regular files being embedded. This CL
relaxes the restriction a little: if the GODEBUG embedfollowsymlinks=1
is set, we allow the leaf files being embedded (not the directories
containing them) to be symlinks. The files pointed to by the symlinks
must still be regular files.
This will be used when a Bazel build action executing the Go command is
running in a symlink-based sandbox. It's not something we want to enable
in general for now, so it's behind a GODEBUG.
Fixes #59924
