'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
Fixes: b4aff7513df3 ("scripts/gdb: use mem instead of core_layout to get the module address")
