cmd/go: elide -rpath when not applicable and used via LDFLAGS

Some linker flags should only be applied when performing the final
linking step for a shared library or executable, etc. In other
contexts, they're either invalid, or meaningless to apply (so should
not be specified).

When an external linker is used (either directly by Go or by the
compiler driver used by cgo), -rpath and -rpath-link should only be
specified in the final linking step.  On platforms such as Solaris,
ld(1) will reject its use in any other scenario (such as when linking
relocatable objects).

This change is necessary because Go does not currently offer a way to
specify LDFLAGS based on when they should be applied.

Fixes #12115
