security/trousers: Fix compilation with LibreSSL

This was causing the build of security/gnutls to fail when the
TPM option was enabled and make.conf contained
DEFAULT_VERSIONS+=ssl=libressl. The gnutls configure script failed to
successfully link against the libtspi.so library, and therefore
determined the tss library was not suitable and disabled TPM.
/usr/local/lib/libtspi.so: undefined reference to `RSA_set0_key'
This caused the gnutls build to fail during staging due to an incorrect
PLIST (missing bin/tpmtool).

As of version 0.3.14, TrouSerS utilises the new OpenSSL function
RSA_set0_key, which was only introduced in OpenSSL 1.1.0 and is not in
LibreSSL (yet).

The TrouSerS code utilises the OPENSSL_VERSION_NUMBER preprocessor macro
to determine the version of OpenSSL which is it compiling against,
and defines the RSA_set0_key function if the version of OpenSSL is older
than 1.1.0. This causes an issue with LibreSSL, because it sets the
OPENSSL_VERSION_NUMBER preprocessor macro to impersonate OpenSSL 2.0.0.

The new patch-src_trspi_crypto_openssl_rsa.c causes TrouSerS to define
the RSA_set0_key function on LibreSSL also.
