email: Revert to LDAP auth as pam does not allow non-admin users
Since FreedomBox does not allow any users but those belonging to 'admin' group
to login, using passwd driver for auth means that only admin can login to
postfix/dovecot. Fix this by reverting to using LDAP driver.

email: rspamd: Simplify installing configuration
Existing implementation expects configuration files installed by FreedomBox to
be edited at the top and the bottom. When re-installing, it tries to keep the
edited parts while reinstalling the FreedomBox managed section in the middle to
be overwritten with (new) FreedomBox defaults.

Instead, simply ship the two files to rspamd configuration directories. These
can be easily overridden by the user if they desire due to flexible
configuration file priorities by rspamd.
