Replace assert with propper error handling in rdsquashfs describe
If a SquashFS archive contains file names with '..', '/' or similar nonsense in them, the unpacking code already refuses to process them, but the 'describe' code path simply triggers an assert that might not be there if the binary was compiled with NDEBUG defined. This commit replaces the assert with propper error handling that also reports on why things are failing and adds an additional check in the describe_tree function that tests if the file name is sane.
