libfwupd: Restore recognizing gpg and pkcs7 types still

Browse Source 
The snap-store intends to ship an updated libfwupd library but
to use it with whatever version daemon is on the host system.

This means that the library needs to still work with older metadata
signing types.

This fixes the following error in that scenario:
```Failed to update metadata for lvfs: Keyring kind jcat not supported```
