[bug#63877] [PATCH] gnu: services: web: Set SSL_CERT_DIR in php-fpm environment.

[Timo Wilken <guix@twilken.net>]

Some PHP programs, like Nextcloud, make HTTPS requests to other servers. For
this, they need to know where the system CA certificates are.

* gnu/services/web.scm (php-fpm-shepherd-service): Set SSL_CERT_DIR
  environment variable.
---

This solution adds a dependency from the resulting Shepherd service to the
nss-certs package, which weighs 0.3 MiB. An alternative solution might be to
set SSL_CERT_DIR=/etc/ssl/certs instead and rely on nss-certs being installed
system-wide.
