kexec-tools: Determine if the image is lzma commpressed
Currently there are 2 functions for decompressing compressed image. The
zlib_decompress_file() will determine if the image is compressed by gzip
before read, but lzma_decompress_file() will not. This can cause misleading
information to be printed when the image is not compressed by lzma and
debug option is used:
]# kexec -d -s -l /boot/vmlinuz-5.14.10-300.fc35.x86_64 \
--initrd /boot/initramfs-5.14.10-300.fc35.x86_64.img \
--reuse-cmdline
Try gzip decompression.
Try LZMA decompression.
lzma_decompress_file: read on /boot/vmlinuz-5.14.10-300.fc35.x86_64 of
65536 bytes failed
Add a helper function is_lzma_file() to help behave consistently.
