trace: Update the file header
It seems better to put the TEXT_BASE value in the file header rather than
in an entry record. While it is true that there is a separate base for
pre-relocation, this can be handled by using offsets in the file.
It is useful to have a version number in case we need to change the trace
format again.
Update the header to make these changes.
