scripts/decodecode: fix faulting instruction no print when opps.file is DOS format
If opps.file is in DOS format, faulting instruction cannot be printed:
/ # ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
/ # ./scripts/decodecode < oops.file
[ 0.734345] Code: d0002881 912f9c21 94067e68 d2800001 (b900003f)
aarch64-linux-gnu-strip: '/tmp/tmp.5Y9eybnnSi.o': No such file
aarch64-linux-gnu-objdump: '/tmp/tmp.5Y9eybnnSi.o': No such file
All code

10: b900003f str wzr, [x1]
Code starting with the faulting instruction
===========================================
Background: The compilation environment is Ubuntu, and the test
environment is Windows. Most logs are generated in the Windows
environment. In this way, CR (carriage return) will inevitably appear,
which will affect the use of decodecode in the Ubuntu environment.
The repaired effect is as follows:
/ # ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
/ # ./scripts/decodecode < oops.file
