x11/{linux-nvidia-libs,nvidia-driver}-390: update to version 390.157

Updating 390 series of legacy version of nvidia-driver and
linux-nvidia-libs to 390.157.

This is the last legacy driver that is behind upstream and still lives
in ports tree. So updating these to ease future issues to narrow down
version window.

Tested (by myself) make and make package only, on stable/14, amd64 at
commit 8c991c4b06954371886413d7a4eb2f0569721857 as I myself am not using
390 series of driver and i386 anymore.
