[OE-core] [PATCH 04/20] udev-cache: Don't ignore errors from cache extract

[Ben Shelton]

From: Richard Tollerton <rich.tollerton at ni.com>

Currently, error messages generated during tarball extract are
suppressed. This seems ham-handed, particularly since under normal
operation, the only expected error ought to be the attempted extraction
of pipes, which typically only means /dev/log.

So stop the redirections and add an --exclude=log to suppress the error
message when attempting to extract /dev/log.

This requires CONFIG_FEATURE_TAR_LONG_OPTIONS if using busybox tar.
