[37/87] trace-cmd library: Set log size to the input tep handler when it is read from the file

Commit Message

Setting the long size to the input tep handler in tracecmd_read_headers()
API may be too late, as this tep handler is used to read and parse data
from the file before that. The most suitable place for that is
tracecmd_alloc_fd() API, right after reading the long size from the
file.
