Squashfs: add decompressor entries for lzma and lzo
Add knowledge of lzma/lzo compression formats to the decompressor framework. For now these are added as unsupported. Without these entries lzma/lzo compressed filesystems will be flagged as having unknown compression which is undesirable. Signed-off-by: Phillip Lougher <phillip@lougher.demon.co.uk>
