Makedeb for php7x

[masterjus]

Currently I had few problems:

• phpredis from apt repository doesn't installs for php-fpm
• existing ansible roles to install phpredis doesn't work because of very old mkdeb.sh

Current changes makes possible to make .deb package which will install phpredis for php-cli and php-fpm

It autodetects currently installed php version and makes package for it.

It automatically sets phpredis version (must be started from number, so "develop" will not work) from php_redis.h file.

Hey @masterjus, thank you for your pull request.
Unfortunately I don't want to accept this PR because I think that people should use deb and rpm packages from official repos for their distros.
@michael-grunder what do you think?

@yatsukhnenko
it doesn't exists for php7.x-fpm.
This why I've started this activity.

I want to install this package by ansible but the only way is to compile it from source. But this is bad solution.

@yatsukhnenko People are still free to use official packages. Doesn't seem to hurt anything to have a script in the repo.

@michael-grunder I don't know anything about deb packages so I can't check changes in this PR. Could you review it?
