populate_sdk_ext.bbclass: add ESDK_MANIFEST_EXCLUDES

Add ESDK_MANIFEST_EXCLUDES to enable excluding items from sdk-conf-manifest.

By default, files under conf/ are all added to sdk-conf-manifest, as the manifest file is set to 'conf/*'.

However, there are situations where some configuration files under conf/ directory are not intended to be added to sdk-conf-manifest, thus adding ESDK_MANIFEST_EXCLUDES to enable users to do this.

This variable takes the form of glob matching.
e.g.
ESDK_MANIFEST_EXCLUDES = "conf/autogen*"
This would exclude all files under conf/ starting with 'autogen' from sdk-conf-manifest.
