[PATCH 2/3] rsyslog: add disabled PACKAGECONFIG to drop capabilities

[Randy MacLeod <Randy.MacLeod@windriver.com>]

Add PACKAGECONFIG to enable dropping capabilities but leave it as disabled
to follow upstream and avoid a systemd issue described below.

rsyslog-8.2302 added a configure option to drop capabilities from
full to:
   chown, dac_override, setgid, setuid, setpcap, net_bind_service,
   net_admin, ipc_lock, sys_chroot, sys_admin, sys_resource, lease,
   syslog, block_suspend
This works fine and passes ptests with sysvinit however
there is a bug when using systemd that breaks some tests:
    https://github.com/rsyslog/rsyslog/issues/5091
Therefore only add a non-default PACKAGECONFIG option in keeping
with the rsyslog upstream.

One can install libcap-ng-bin to run pscap to see the capabilities.

Without this option the ptest result with systemd as init is:
    Version | Passed | Failed | Skipped
     8.2302 | 473    |      0 |       3
