tools/syz-trace2syz: only add null-byte for prog.BufferFilename
trace2syz used to always add a null byte to strings.
This isn't correct behavior since we may end up writing null bytes to files.
The extra byte can affect system calls like ioctl FS_IOC_ENABLE_VERITY.
We now only add the byte for filenames.
