Always print the kernel UUID and load address if we are working with

a kernel binary - even if we can't find the symbol-rich binary or 
dSYM on the debugger-system.  Print a warning if the symbol-rich binary
cannot be located.  This more closely emulates the gdb behavior when
a kernel debug session failed to locate a kernel binary.
