    common/symbols: Remove print_symbol() and associated infrastructure
    
    Also adjust the one common user of print_symbol() to use the new printk()
    format.  While adjusting the format string, increase the width so a
    long-to-expire plt_overflow() timer doesn't break the column alignment.
