    pkcs11: fix racy build
    
    seahorse-pkcs11.h needs to be built before the files that include it are
    compiled. Unfortunately it is generated by valac, and there doesn't seem
    to be any simple way to tell this to Automake. But adding the Vala stamp
    file to BUILT_SOURCES tells it to compile the Vala before doing anything
    else, which is what we need.
