[Buildroot] [PATCH] package/libssh: fix select BR2_PACKAGE_LIBOPENSSL_ENGINES

BR2_PACKAGE_LIBSSH_OPENSSL unconditionnally selects
BR2_PACKAGE_LIBOPENSSL_ENGINES even though libressl is also supported
as an OpenSSL provider (and BR2_PACKAGE_LIBOPENSSL_ENGINES doesn't
make sense for libressl).

This causes the following Kconfig warning:

WARNING: unmet direct dependencies detected for BR2_PACKAGE_LIBOPENSSL_ENGINES
  Depends on [n]: <choice> && BR2_PACKAGE_LIBOPENSSL [=n]
  Selected by [y]:
  - BR2_PACKAGE_LIBSSH_OPENSSL [=y] && <choice> && BR2_PACKAGE_OPENSSL [=y]

We checked that libssh, with OpenSSL support and libressl selected as
an OpenSSL provider works fine, using the following defconfig:

BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_GLIBC_STABLE=y
BR2_PACKAGE_LIBSSH=y
BR2_PACKAGE_LIBSSH_SERVER=y
BR2_PACKAGE_LIBRESSL=y
