kmod: enable openssl support by default

kmod: enable openssl support by default

linux-yocto kernel adds openssl-native dependency by default even
when module signing is still optional. kmod should enable
openssl support too. This helps see details of signed kernel
modules and debug issues with module signing. For small systems
this can still be disabled.

modinfo output shows bad signing info when kernel signing is enabled
but openssl support is missing from kmod:
