init: drop unused direct dependency on libcrypto.so

When I previously tried this in https://r.android.com/1108553 , it broke on
some targets but I think that may have been fixed. I'm trying it again now
to see if this now passes treehugger and sticks.

Note: There is still an indirect dependency via libfs_mgr.
