Date: Tue, 5 Nov 2024 12:50:35 +0100

When Compressed RAM block device support is disabled, the
CONFIG_ZRAM_DEF_COMP symbol still ends up in the generated config file:

    CONFIG_ZRAM_DEF_COMP="unset-value"

While this causes no real harm, avoid polluting the config file by
adding a dependency on ZRAM.
