meson_options.txt: disable the "smbclient" plugin by default

The bug https://bugzilla.samba.org/show_bug.cgi?id=11413 makes MPD crash after at most a minute of using the plugin. Since this bug is five years old already and it doesn't look like it will ever be fixed, all libsmbclient code in MPD is scheduled for removal. For now, the plugin is disabled by default so people are less likely to hit the crash bug. Closes https://github.com/MusicPlayerDaemon/MPD/issues/991
