File multipath-tools-use-pthread_sigmask-in-alias of Package multipath-tools

commit 928c0261d52bd527c17ae2a67a9034fba66c09b2
Author: Hannes Reinecke <hare@suse.de>
Date:   Fri Mar 20 12:40:38 2009 +0100

    Use pthread_sigmask in alias.c when in daemon mode
    
    sigprocmask is undefined when running multithreaded.
    So we should rather use pthread_sigmask() here when
    we're being called from the daemon.
