SYSDB: Fixing of sudorule without a sudoUser
This patch solved a regression caused by the recent patches
to lowercase sudoUser -- in case sudoUser is missing completely,
we abort the processing of this rule and all others.
With this patch, we return ERR_MALFORMED_ENTRY and gracefully
skip the malformed rule instead.
