[oe] [meta-networking][PATCH] net-snmp: fix the invalid -fdebug-prefix-map

[mingli.yu at windriver.com]

From: Yu Mingli <mingli.yu at windriver.com>

The previous path value to -fdebug-prefix-map
is null which may result in other package such as
quagga do_config error as below:
====================================================
add DISTRO_FEATURES_append = " snmp" to conf/local.conf
