package/luvi: bump to version 2.9.0 to fix build with OpenSSL 1.1.1a

Bump to latest release that bundles lua-openssl 0.7.4 to fix compatibility
with OpenSSL 1.1.1a.

Drop patches 0001 and 0002 that are included in the new release.

Successfully build and runtime tested on Banana Pro, note that version string
for lua-openssl does not match the tag name (0.7.4):

```
luvi v2.9.0
zlib: 1.2.11
libuv: 1.25.0
ssl: OpenSSL 1.1.1a  20 Nov 2018, lua-openssl 0.7.3
```
