    fix bashism in tools/linux/hal-system-lcd-get-brightness-linux
    
    In [1] we got a report that LCD brightness setting does not work on
    Sony Vaio laptops. This is due to the 'let = ...' syntax which is a
    bashism, but the script has a /bin/sh hashbang.
    
    I replaced the let by its POSIX counterpart.
    
    Thanks,
    
    Martin
