rpm2cpio.sh: make compression tests case-insensitive
In the rpm2cpio.sh script, the output of $COMPRESSION is tested for certain lowercase strings such as 'xz' in order to determine the decompression to use. The problem is that the output strings tested are from the output of 'file', which uses different cases in different versions e.g. file-5.09 prints: tmp/sysroots/x86_64-linux/usr/bin$ ./file xxx.tar.xz: XZ compressed data while file-5.03 prints: tmp/sysroots/x86_64-linux/usr/bin$ ./file xxx.tar.xz: xz compressed data In the former, the XZ string causes xz compressed payloads to incorrectly fall through to the catch-all lzma case.
