x86/vdso: Only enable vDSO retpolines when enabled and supported
When I fixed the vDSO build to use inline retpolines, I messed up
the Makefile logic and made it unconditional. It should have
depended on CONFIG_RETPOLINE and on the availability of compiler
support. This broke the build on some older compilers.
