s390: fix -Wundef warning for CONFIG_KERNEL_ZSTD
Since commit 80b6093b55e3 ("kbuild: add -Wundef to KBUILD_CPPFLAGS
for W=1 builds"), building with W=1 detects misuse of #(el)if.
$ make W=1 ARCH=s390 CROSS_COMPILE=s390x-linux-gnu-
[snip]
arch/s390/boot/decompressor.c:28:7: warning: "CONFIG_KERNEL_ZSTD" is not defined, evaluates to 0 [-Wundef]
28 | #elif CONFIG_KERNEL_ZSTD
| ^~~~~~~~~~~~~~~~~~
This issue has been hidden because arch/s390/boot/Makefile overwrites
KBUILD_CFLAGS, dropping -Wundef.
CONFIG_KERNEL_ZSTD is a bool option. #elif defined() should be used.
The line #ifdef CONFIG_KERNEL_BZIP2 is fine, but I changed it for
consistency.
