Horst Kronstorfer a6e6c60e3a dtc: Fix zero-length input segfault ...

This patch fixes a segmentation fault caused by dereferencing a NULL
pointer (pos->file aka yylloc.file) in srcpos_string when the input
length is 0 (fe 'dtc </dev/null'.) Reason: yylloc.file is initialized
with 0 and the tokenizer, which updates yylloc.file via srcpos_update
doesn't get a chance to run on zero-length input.
