cmd/go: extend the linker -o workaround for plugins to all platforms

On Linux, for a shared object, at least with the Gold linker, the
output file path is recorded in the .gnu.version_d section. When
the output file path is in a temporary directory, it causes
nondeterministic build.

This is similar to #58557, but for Linux with the Gold linker.
Apply the same workaround as in CL 477296.

Should fix the linux-arm64-longtest builder.
