package/libssh2: fix dependency on libgcrypt

Since 2f89476 (package/libgpg-error: bump to version 1.23), libssh2 has
inherited the dependency from libgcrypt (propagated from libgpg-error).

However, since libssh2 can use either openssl or libgcrypt as a backend,
the dependency should be relaxed when openssl is available.

But the test is broken and inverted: it will make libssh unavailable as
soon as openssl is enabled.

Fix this dependenc byt doing what other similar packages do: select
openssl if the other crypto backend (here libgcrypt) is not enabled.
This also allows us to drop the propagated dependency on the arch
condition.
