libcurl passes an empty line to header_callback indicating the end
of the response's HTTP headers.
Currently this empty line is printed to the debuginfod_client's
verbose_fd with a "header" prefix:
$ echo $DEBUGINFOD_URLS
https://debuginfod.fedoraproject.org/
$ debuginfod-find -vv debuginfo e2bbf033b548021c37866429f12a99bd33bd6e8d
[...]
header x-fedora-requestid: ZULLx0PPA8nmj8c8Hw-RtAACgAE
header server: Apache
header
[...]
Prevent this unnecessary line of output by only printing non-empty
lines in header_callback.
