openssl: Remove patch already upstreamed

Since the bump to OpenSSL 3.3.1, riscv32 doesn't build anymore due to
the folowing error:
crypto/riscv32cpuid.s:77: Error: symbol `riscv_vlen_asm' is already
defined

This is due to the patch beeing already applied upstream:
Commit: 8702320db98d1346c230aff1282ade3ecdca681a
