xz: Fix a bug with --files and --files0 in raw mode without a suffix.
The following command caused a segmentation fault:
xz -Fraw --lzma1 --files=foo
when foo was a valid file. The usage of --files or --files0 was not
being checked when compressing or decompressing in raw mode without a
suffix. The suffix checking code was meant to validate that all files
to be processed are "-" (if not writing to standard out), meaning the
data is only coming from standard in. In this case, there were no file
names to check since --files and --files0 store their file name in a
different place.
Later code assumed the suffix was set and caused a segmentation fault.
Now, the above command results in an error.
