So-so ... if the file contents are modified, but the environment
variable that points to the file is fixed, then one may get into parse
race conditions as different debuginfod client objects in the process
may be active at the same time.

I see some value in doing this sort of thing more broadly,
hypothetically, but it's vague/speculative enough that I'd be just as
glad to limit the concept to the present case ("also add all headers
in given file").  So how about a $DEBUGINFOD_HEADERS and perhaps
$DEBUGINFOD_HEADERS_FILE env vars for now?
