[OE-core][dunfell 01/21] sanity: Verify that user isn't building in PSEUDO_IGNORE_PATHS

["Steve Sakoman" <steve@sakoman.com>]

From: Dorinda <dorindabassey@gmail.com>

If a user builds in a path in PSEUDO_IGNORE_PATHS, random failures
are generated. Hence this patch adds a sanity check in sanity.bbclass
to ensure that a user isn't building in PSEUDO_IGNORE_PATHS.

[YOCTO #14179]
