scripts: pre-submit: Limit file descriptors for valgrind

Valgrind complains and exits with an error if the limit is "too large":

    --426:0:libcfile Valgrind: FATAL: Private file creation failed.
       The current file descriptor limit is 1073741804.
       If you are running in Docker please consider
       lowering this limit with the shell built-in limit command.
    --426:0:libcfile Exiting now.
