fix: fixed the posible read of NULL when strdup fails thus resulting in

Browse Source 
rpl->filename being NULL by setting an error signalling that we ran out
of memory to ease the debugging of the mariadb_rpl_options function and make
it clearer if it ever fails because of this. Also added va_end in this case to
avoid the va_list (ap) leaking when we return from this function and
then returning 1 from the fucntion.
