libchromeos-ui: Increase hard limit of file descriptors to 16384
Increase hard limit of file descriptors to 16384 (default is otherwise 4096).
Native GPU memory buffer requires a FD per texture. Current 2048 hard limit can
be reached in the wild under some circumstances.
Note: it's the amount of 4GB 256x256 textures.
