[OE-core] [PATCH] xorg-proto-common: allow the empty package

[jackie.huang at windriver.com]

From: Jackie Huang <jackie.huang at windriver.com>

Allow the ${PN} package to be created empty to avoid error like:
ERROR: bigreqsproto not found in the base feeds (intel_x86_64 core2-64
x86_64 noarch any all).
