Add -z,lazy to LDFLAGS

This fixes undefined symbol errors on platforms where -z,lazy may not be the default.

Given the errors, it doesn't look like we can just set this for all builds that link to this. It needs to be set on the go build command line.

Probably the safest fix would be to use dlsym() to load the libnvidia-ml.so functions, instead of kinda-linking-against-it-but-not-really and relying on lazy binding

We had a user run into this today in Gentoo. Gentle ping, would love to see this in. It'd make things much easier than trying to workaround it in all consumers.

(Unfortunately, the CI logs have expired, so I can't comment on fixing those right now.)

As @klueska points out. This is not the right place to do this. It needs to be added explicitly in the application being built.
