[Buildroot] [PATCH] package/vsftpd: fix build with libressl

[Francois Perrad]

Fixes the following error:
ssl.c: In function 'ssl_init':
ssl.c:98:18: error: 'SSL_OP_NO_TLSv1_3' undeclared (first use in this function); did you mean 'SSL_OP_NO_TLSv1_1'?

in ssl.h (libressl), the definition of SSL_OP_NO_TLSv1_3 is under the condition LIBRESSL_HAS_TLS1_3 or LIBRESSL_INTERNAL

with libopenssl, this definition is unconditional

this issue appears with vsftpd 3.0.4
