Currently luasec fails to build if OpenSSL was built without compression
support due to an undefined COMP_METHOD type:

    ssl.c: In function 'meth_compression':
    ssl.c:404:9: error: unknown type name 'COMP_METHOD'
       const COMP_METHOD *comp;
             ^
    <builtin>: recipe for target 'ssl.o' failed
    make[6]: *** [ssl.o] Error 1

Add a local patch to stub the `meth_compression()` function if there is no
compression support available in the OpenSSL library in order to allow
luasec to build.

A similar fix has been added upstream with
https://github.com/brunoos/luasec/pull/30

Noted in luasec 0.4.1 Changelog:
Activate SSL_MODE_RELEASE_BUFFERS by default if it is available (thanks Prosody project)

Update to latest 0.5 to fix a few other leaks.
luasec moved to github, so update URL and license info.
Move package maintainer to correct place in Makefile, hope he is okay with it.
