[oe] [PATCH][meta-webserver] apache2: add PACKAGECONFIG for selinux

[wenzong.fan at windriver.com]

From: Wenzong Fan <wenzong.fan at windriver.com>

Add PACKAGECONFIG for 'selinux', otherwise there would be warnings like
below:

WARN: apache2: apache2 rdepends on libselinux, but it isn't a build dependency?
