Subject: [PATCH] fix build with libressl

SSL_set0_rbio is provided by libressl since version 3.4.0 and
https://github.com/libressl-portable/openbsd/commit/c99939f9665a9c3c648682b4987df46600b70efc
but SSL_set0_wbio is not provided resulting in the following build
failure:

/nvmedata/autobuild/instance-9/output-1/host/lib/gcc/s390x-buildroot-linux-gnu/10.3.0/../../../../s390x-buildroot-linux-gnu/bin/ld: check/libcheck.a(check_ssl.o): in function `ssl_connect':
check_ssl.c:(.text+0x7da): undefined reference to `SSL_set0_wbio'

Fixes:
