    build: Drop pointless -Wformat-security warning flag
    
    We already set -Wformat=2, which implies -Wformat-security, so there’s
    no need to test for and set -Wformat-security separately.
    
    The test for -Wformat-security never worked anyway, since gcc complains
    if it’s specified without also setting -Wformat to some value. The
    complaint causes configure.ac/meson.build to assume the option doesn’t
    work.
