Pacify --temp flag when running in server mode

This caused some confusion for the granite 34b llamafiles, which specify
the temperature flag in the .args file. While it worked fine for the CLI
mode of operation, if you ran the llamafile without arguments, then it'd
fail with an error message instead of running the server :'(
