scripts/gdb: fix 'lx-lsmod' show the wrong size

'lsmod' shows total core layout size, so we need to sum up all the
sections in core layout in gdb scripts.

/ # lsmod
kasan_test 200704 0 - Live 0xffff80007f640000

Before patch:
(gdb) lx-lsmod
Address Module Size Used by
0xffff80007f640000 kasan_test 36864 0

After patch:
(gdb) lx-lsmod
Address Module Size Used by
0xffff80007f640000 kasan_test 200704 0
