Change build_machine to host_machine for freebsd specific configuration.

Allow building the test on a FreeBSD build host even if no "OpenSSL" since the base OpenSSL will suffice.

OPENSSL_init_ssl only exists since version 1.1.0.

Dependency on libcrypto neither necessary nor desirable if using the builtin openssl (it world require the ports version to be installed instead.)

Depend on host_machine rather than build_machine to account for potential cross compilation.

Look for the openSSL libs in /usr/local first.

Fix for OpenSSL 3

Whatever in meson/FreeBSD was unhappy about the basic library dependency for libcrypto seems to have been fixed because it's working for me in all tests I've done in it's basic form. Also removing the version check since nothing should be using the wildly out of date openssl.

…private change is the right

answer.  I did not make changes to the depends method(s) since that seemed to make the Debian
based builds very unhappy (couldn't find libcrypto) and everything else seems to generate reasonable
pkg_config files without invoking method.
