scripts/gdb: change kernel config dumping method 



[ Upstream commit 1f7a6cf6b07c74a17343c2559cd5f5018a245961 ]

MAGIC_START("IKCFG_ST") and MAGIC_END("IKCFG_ED") are moved out
from the kernel_config_data variable.

Thus, we parse kernel_config_data directly instead of considering
offset of MAGIC_START and MAGIC_END.

Fixes: 13610aa9 ("kernel/configs: use .incbin directive to embed config_data.gz")
