gnu: rspamd: Update to 3.2

* gnu/packages/mail.scm (rspamd): Update to 3.2

I also added a new build option, that changes the LOCAL_CONFDIR variable to
/etc/rspamd. This allows for rspamd configuration via the /etc/rspamd/local.d
and override.d directories, which by default were located in the PREFIX which
is in /gnu/store.
