On systems honouring, by default, the deprecation of SHA1, such as AlmaLinux 9, xrdgsiproxy fails (see issue #1992).
This patch replaces use of SHA1 by SHA-256 for signatures. SHA-256 is supported by all OpenSSL versions still around,
which makes it easier from point of view of portability. Move to SHA3 should be considered for the future.

Fixes #1992.
