Beta 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 can't load main page after a clean install. 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.
