trace-cmd library: Set the correct file state when reading file with no kallsyms

The kallsyms section of the trace file can contain no data, this is
valid use case. When such file is read and parsed by read_proc_kallsyms(),
the file state should be set to TRACECMD_FILE_KALLSYMS in that case.

Renamed a local variable from pevent to tep, to be consistent with the
libtraceevent prefix.
