libcrypto: compile all PIC objects with -DOPENSSL_PIC -fPIC

This change modifies the libcrypto PIC objects to always compile with
`-DOPENSSL_PIC -fPIC` to restore parity with the upstream build process.
This ensures that the legacy provider is built with parity to the
upstream legacy provider.

MFC after:              12 days
Tested with:		`make check` (legacy provider), `make universe`
