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.
