[PATCH] package_manager: warn that PACKAGE_EXCLUDE doesn't work for opkg

[Ross Burton <ross.burton@intel.com>]

The rpm and dpkg package managers both support package exclusion at install
time, which we expose though the PACKAGE_EXCLUDE variable.  However opkg doesn't
support this, so show a warning if PACKAGE_EXCLUDE is used with file systems
built using opkg.
