Subject: [RFC PATCH mtd-utils 006/110] ubifs-utils: Clean up error message printing functions

Functions 'err_msg' and 'sys_err_msg' are almost same with 'errmsg' and
'sys_errmsg', since 'errmsg' and 'sys_errmsg' can print programe name,
so replace error message printing functions (ubifs-utils) with common
lib functions(include/common.h).
