[OE-core] [PATCH v4] opkg-utils: Change alternatives lib path from /usr/lib/opkg to /var/lib/opkg

[Li Zhou]

When update-alternatives is moved from opkg to opkg-utils, a line in
the file is changed
from <ad="$OPKG_OFFLINE_ROOT at opkglibdir@/opkg/alternatives">
to <ad="$OPKG_OFFLINE_ROOT/usr/lib/opkg/alternatives">.
But opkglibdir doesn't equal to "/usr/lib" here, but equal to "/var/lib"
 in oe-core build by configuring --with-opkglibdir.
opkg-utils can't get the var value in opkg, so here define OPKGLIBDIR to
set the path.
