Subject: [PATCH] Moved os-compatibility and added header

* Moved os-compatibility.c to util
* Added header under util
* Removed static since it isn't needed (i think so)
* Adjusted meson.build to include lib_wlr

Improved some codestyle

* Added guard to os-compatibility.h
* Fixed typo in include statment

Adjusted Guard

* Changed guard to _WLR_UTIL_OS_COMPATIBILITY
