selinux: improve debug configuration
If the SELinux debug configuration is enabled define the macro DEBUG
such that pr_debug() calls are always enabled, regardless of
CONFIG_DYNAMIC_DEBUG, since those message are the main reason for this
configuration in the first place.
Mention example usage in case CONFIG_DYNAMIC_DEBUG is enabled in the
help section of the configuration.
