scripts/checkstack.pl: fix arm sp regex

if objdump has below entries;
c01ed608 <X>:
c01ed614:       e24ddff7        sub     sp, sp, #120    ; 0x78

c01f0d50 <Y>:
c01f0d50:       e24dd094        sub     sp, sp, #140    ; 0x8c

scripts fails to read stack usage.
so making regex $re for ARM similar to aarch64
