pseudo: support multiple search directories in PSEUDO_PASSWD
This makes it possible to use --without-passwd-fallback when building images where the preferred passwd files are not available until after installation has begun. Signed-off-by: Peter A. Bigot <pab@pabigot.com>

+Subject: [PATCH 3/3] pseudo_client.c: support multiple directories in
+ PSEUDO_PASSWD
+
+For OpenEmbedded it is highly unlikely that using the build host passwd
+file is the right approach. Most packages can be built with a pseudo
+that was configured --without-passwd-fallback, since
+PSEUDO_PASSWD=${STAGING_DIR_TARGET} suffices.
+
+This fails when building images, because image.bbclass (correctly)
+overrides to PSEUDO_PASSWD=${IMAGE_ROOTFS}. However, the rootfs
+/etc/passwd is not created until the post-install phase of base-passwd,
+which is long after a passwd file is required. For example, the smart
+RPM interface wants to look up uid 0 right away. The right solution
+here is to look first in ${IMAGE_ROOTFS}, then fallback to
+a location holding immutable files with the minimum user/group settings
+necessary to successfully get base-passwd onto the target.
+
+Rather than rework pseudo to change PSEUDO_PASSWD_FALLBACK to be a
+run-time rather than compile-time specification, rework the handling of
+PSEUDO_PASSWD so that it is a colon-separated list of directories that
+are processed in order.
