[OE-core] [PATCH 1/1] sstate.bbclass: fix parallel building issue

[rongqing.li at windriver.com]

From: "Roy.Li" <rongqing.li at windriver.com>

sstate_package creates hardlink from sysroot to SSTATE_BUILDDIR, then
sstate_create_package will store SSTATE_BUILDDIR into a archive file by
tar, but once other packages install the same file into sysroot, the
creating the archive file will fail with below error:

    DEBUG: Executing shell function sstate_create_package
    tar: x86_64-linux/usr/share/aclocal/xorg-macros.m4: file changed as we read it

This kind of error is harmless, use --ignore-failed-read to ignore it.
