The asymmetric key subtype is only used by the key subsystem that cannot
itself be a loadable module, so when ASYMMETRIC_PUBLIC_KEY_SUBTYPE is set
to =m, it just does not get used. It also produces a compile-time warning:
WARNING: modpost: missing MODULE_LICENSE() in security/integrity/ima/ima_asymmetric_keys.o
Make this a 'bool' symbol to avoid both problems.
Fixes: 88e70da170e8 ("IMA: Define an IMA hook to measure keys")
