scripts/gdb: change kernel config dumping method 

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: 13610aa908 ("kernel/configs: use .incbin directive to embed config_data.gz")
