wpa_supplicant_8: fix keystore-backed keys

The switch to BoringSSL broke keystore backed keys because I didn't
realise that wpa_supplicant was using the dynamic ENGINE loading to load
the keystore module.

The ENGINE-like functionality in BoringSSL is much simplier and this
change should enable it. However, I don't have a suitable AP to test
against.
