sftp doesn't build with libressl >= 3.5.0 resulting in the following
build failure since commit 8b216927db080b38fdbf1f8b025b6f90a89d4bc2:

mac.c: In function 'init_mac':
mac.c:189:3: warning: implicit declaration of function 'HMAC_CTX_init'; did you mean 'HMAC_CTX_new'? [-Wimplicit-function-declaration]
  189 |   HMAC_CTX_init(hmac_ctx);
      |   ^~~~~~~~~~~~~
      |   HMAC_CTX_new
mac.c: In function 'set_mac_key':
mac.c:435:14: error: storage size of 'ctx' isn't known
  435 |   EVP_MD_CTX ctx;
      |              ^~~

So force use of openssl for sftpd, as no feedback was received on
https://github.com/proftpd/proftpd/pull/1481
