Add arg.gni to help with rename to libvulkan.so.1
We want to unify our BUILD.gn with upstream's, and that includes
renaming libvulkan.so to libvulkan.so.1 on Linux. Some code in src/
depends in the libvulkan.so filename, so we need to add an arg.gni so we
can flip the switch those dependencies over atomically.
