build: generate src/NetworkManager.ver during build

This adds 0.4 seconds to the build time.

You can disable it by setting $NM_BUILD_NO_CREATE_EXPORTS environment
variable. This is useful in the unexpected case that the script
is broken.
Or, if you just want to use a different, non-generated version-script.
Or, if you want to save 0.4 seconds build-time.
