    Revert "configs: Disable time namespaces"
    
    This reverts commit dda343646c87c0936daf12ba10236c83effc7546.
    
    It turned out that disabling time namespace breaks the kernel badly,
    userspace randomly gets asserts from glibc on malloc()/free()
    and fails.
    
    Resurrect time namespace support in kernel like it's by default in
    RHEL8.4.
    May be later we'll fix the kernel to work properly evern without time ns
    support, but this is another story.
