kexec-tools: fix multiple compile errors
Add two patches to fix compile errors being repeatedly seen on OpenWrt CI.
The first is an upstream backport to fix this i386-related error:
x86_64-openwrt-linux-musl-gcc -mcmodel=large -I./purgatory/include
-I./purgatory/arch/x86_64/include -I./util_lib/include -I./include -Iinclude
-I/builder/shared-workdir/build/sdk/staging_dir/toolchain-x86_64_gcc-13.3.0_musl/lib/gcc/x86_64-openwrt-linux-musl/13.3.0/include
-c -MD -o purgatory/arch/i386/entry32-16.o purgatory/arch/i386/entry32-16.S
purgatory/arch/i386/entry32-16.S: Assembler messages:
purgatory/arch/i386/entry32-16.S:23: Error: 64bit mode not supported on `i386'.
The second addresses an error using basename() on musl libc:
kexec/arch/i386/x86-linux-setup.c: In function 'add_edd_entry':
kexec/arch/i386/x86-linux-setup.c:332:20: warning: implicit declaration of function 'basename' [-Wimplicit-function-declaration]
332 | if (sscanf(basename(sysfs_name), "int13_dev%hhx", &devnum) != 1) {
| ^~~~~~~~
kexec/arch/i386/x86-linux-setup.c:332:20: warning: passing argument 1 of 'sscanf' makes pointer from integer without a cast [-Wint-conversion]
332 | if (sscanf(basename(sysfs_name), "int13_dev%hhx", &devnum) != 1) {
| ^~~~~~~~~~~~~~~~~~~~
