Remove connman-plugin-session-policy-local

A packagegroup-agl-core-connectivity require to connman-plugin-session-policy-local in all case.
On the other hand, connman-plugin-session-policy-local is enabled in case of AGL_FEATURES with aglcore.
When the meta-agl use without aglcore, building for packagegroup-agl-core-connectivity will fail.
This patch remove to connman-plugin-session-policy-local in all case.
Because connman-plugin-session-policy-local is not using.
