redhat/configs: Enable CONFIG_CRASH_DM_CRYPT on RHEL

JIRA: https://issues.redhat.com/browse/RHEL-104939

Upstream Status: RHEL-only

With this option enabled, user space can interact with
/sys/kernel/config/crash_dm_crypt_keys to make the dm crypt keys
persistent for the dump-capture kernel.

Note CONFIG_SYSFS has already been enabled by default. But somehow
enabling CONFIG_CRASH_DM_CRYPT triggers the following error,
    0:11:04 Found unset config items in arm64 rt-debug-rhel, please set them to an appropriate value
    00:11:04 CONFIG_SYSFS=y
    ...
    00:11:04 make[1]: *** [Makefile:607: dist-configs-check] Error 1
    00:11:04 make[1]: Leaving directory '/builds/11318547917/workdir/redhat'
    00:11:04 make: *** [makefile:12: dist-srpm] Error 2

So set CONFIG_SYSFS=y explicitly.
