rsnapshot: fix rsnapshot.conf.default

This change is used for fixing cmd path in rsnapshot.conf.default.

The options --without-* disable checking command * on host and get
the default path used, otherwise the host path will be injected into
target configs.

The runtime dependencies to ssh, logger, cp, du are optional and
could be customized in rsnapshot.conf, so it's not needed that
using PACKAGECONFIG to define the runtime dependencies.

+Subject: [PATCH] fix cmd_rsync
+
+Don't break configure if rsync is not installed on host.
+
+rsync is a runtime dependency and this change is only used for
+generating rsnapshot.conf.default. It allows cmd_rsync to use
+default path if options --without-rsync is specfied.
