SPDX identifier of genroot.sh and genserv.sh (not sure which license it's under)

[samueloph]

Hello,

After the much appreciated work done by upstream of adding SPDX identifiers to pretty much all of the files, I decided to do a review of Debian's machine readable d/copyright for curl, and spotted a couple of files with no SPDX identifier from an author which is not curl's upstream.

The files are the following:
https://github.com/curl/curl/blob/7be53774c41c59b47075fbaf758b1497f70b25d6/tests/certs/scripts/genroot.sh
https://github.com/curl/curl/blob/7be53774c41c59b47075fbaf758b1497f70b25d6/tests/certs/scripts/genserv.sh

Both have this header:

# (c) CopyRight 2000 - 2020, EdelWeb for EdelKey and OpenEvidence
# Author: Peter Sylvester

With no license declaration, so I'm not sure what the SPDX header is supposed to set and didn't want to submit a PR.

I took the assumption that both files are under the curl license on Debian (as there isn't any other license shown), but decided to report this so you could double check and possibly add the SPDX header.

Thank you,

Yeah, we have a wildcard in `.reuse/dep5':

curl/.reuse/dep5

Files: tests/data/test* tests/certs/* tests/stunnel.pem tests/valgrind.supp

... but sure, shell scripts should have the SPDX properly spelled out. Will fix!
