eglibc: migrate configurability from oe

Migrate configurability from oe, try to shrink minimal image size

All eglibc configuration options are included in conf/distro/include/default-distrovars.inc.
Define DISTRO_FEATURES_LIBC and DISTRO_FEATURES in local.conf with the same way
in local.conf.sample.extended to enable those options.
