scripts/gdb: add kernel config dumping command
lx-configdump <file> dumps the contents of the gzipped .config to a text file when the config is included in the kernel with CONFIG_IKCONFIG. By default, the file written is called config.txt, but it can be any user supplied filename as well. If the kernel config is in a module (configs.ko), then it can be loaded along with symbols for the module loaded with 'lx-symbols' and then this command will still work. Obviously if you have the whole vmlinux then this can also be achieved with scripts/extract-ikconfig, but this gdb script can be useful to confirm that the memory contents of the config in memory and the vmlinux contents on disk match what is expected.
