BugLink: https://bugs.launchpad.net/bugs/1766823 zram is an useful module for memory constrained systems. However it's imposibble for KVM kernel user to use it. Enable the CONFIG_ZRAM and other related configs like in generic kernel to make it available for KVM kernels, so that it can pass the ubuntu_zram_smoke_test in the SRU regression test suite.
