[OE-core] [PATCH 1/4] classes/populate_sdk_ext.bbclass: handle if local.conf doesn't end with a newline

[Paul Eggleton]

If there is no newline at the end of local.conf, appending
INHERIT = "uninative" won't work, it will corrupt the line and the
installed eSDK will build things, making the "Preparing build system..."
step take an age.

Fixes [YOCTO #8897].
