libweston: fix building issue when EGL support is not enabled

weston-egl-ext.h has been include in compositor-xx.c file in order to
define EGL_PLATFORM_xxx_KHR extensions used by the compositors.
But in case EGL support is not enabled, all EGL related definition must
be skipped except EGL_PLATFORM_xxx_KHR that must be still defined to
allow compositor-xx.c to build.
