libcgroup: fix passing CFLAGS/LDFLAGS to configure

LIBCGROUP_CONF_ENV is a string used to pass environment variables to the
confgiure script, '+=' operator doesn't have any special meaning inside
it, so CFLAGS+=... is passed to shell, overwriting previous CFLAGS
value. Replace CFLAGS+="..." with CFLAGS="$(TARGET_CFLAGS) ...".
