Master Branch additional nginx & php-fpm Cloudflare zlib library prechecks

additional nginx & php-fpm Cloudflare zlib library prechecks

---

Additional checks against GCC native cpu flags to make sure that GCC supports -mpclmul (enabled). Seems some server configurations with older cpus i.e. Intel Xeon Lynnfield 2009 and Xeon Westmere 2010 are returning GCC flags without -mpclmul enabled causing Nginx operation issues when compiled with Cloudflare zlib performance forked library instead of standard zlib libraries https://community.centminmod.com/posts/62818/. This update adds an additional check for pclmul instructions from GCC native output + the existing check for SSE4.2 in /proc/cpuinfo before determining that Cloudflare zlib library can be used for Nginx zlib and PHP-FPM zlib usage. If these 2 checks fail, then Centmin Mod will auto fallback to standard zlib library.
