[PATCH v3 08/41] builtin/mailsplit.c: use error_errno()

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

There's one change, in split_mbox(), where an error() without strerror()
as argument is converted to error_errno(). This is correct because the
previous call is fopen (not shown in the context lines), which should
set errno if it returns NULL.
