Subject: [PATCH] cmake: (re-)add aliases for `add_subdirectory()` builds

Add internal libssh2 library aliases to make these available for
downstream/dependent projects building libssh2 via `add_subdirectory()`:

- `libssh2:libssh2_static`
- `libssh2:libssh2_shared`
- `libssh2:libssh2` (shared, or static when not building shared)
- `libssh2` (shared, or static when not building shared)

Of these, `libssh2` was present in v1.10.0 and earlier releases, but
missing from v1.11.0.

Closes #1169
