[Buildroot] [git commit branch/2026.05.x] package/syslog-ng: needs libopenssl, not libressl

commit: https://gitlab.com/buildroot.org/buildroot/-/commit/69ce103003faa9dfa838aeedf9b9b5734c5e5983
branch: https://gitlab.com/buildroot.org/buildroot/-/tree/2026.05.x

Buildroot commit 51ab6d2290f169f4bb96b8dbbab2d8fb4656766d bumped the
package from version 4.8.3 to 4.11.0. Upstream commit
https://github.com/syslog-ng/syslog-ng/commit/dbe9fb306929168172062a6bc985eb7e38201dab
added the usage of OpenSSL BIO_ functions in version 4.9.0 causing
build errors with LibreSSL:

lib/transport/transport-tls.c: In function 'BIO_s_transport':
lib/transport/transport-tls.c:125:3: error: implicit declaration of
 function 'BIO_meth_set_write_ex'; did you mean 'BIO_meth_set_write'?
 [-Wimplicit-function-declaration]
  125 |   BIO_meth_set_write_ex(meth, _BIO_transport_write);

lib/transport/transport-tls.c:126:3: error: implicit declaration of
 function 'BIO_meth_set_read_ex'; did you mean 'BIO_meth_set_read'?
 [-Wimplicit-function-declaration]
  126 |   BIO_meth_set_read_ex(meth, _BIO_transport_read);

because LibreSSL does not provide these functions.
