    tools/libxc: Correct XC_DOM_PAGE_SIZE() to return a long long
    
    c/s abdf3c5b "libxc: create p2m list outside of kernel mapping if supported"
    introduces a use which Coverity objects to; an int used to mask a uint64_t.
    
    The result needs to be signed to allow ~XC_DOM_PAGE_SIZE() to function
    correctly, and long long to function properly in 32bit builds.
