commit c54d51c78fb995df7b3ba7da148ef8203c9166eb

    chrony: fix build failure for arma9
    
    Eliminate references to syscalls not available
    for ARM_EABI.  Also add a dependency on libseccomp
    which is needed for scfilter to work.
    
    Set PACKAGECONFIG to not enable scfilter, since
    kernel CONFIG_SECCOMP is unlikely to be set.  This
    aligns the usage of libseccomp with that of other packages.
