We're periodically seeing uvesafb timeouts on the autobuilder. Whitelist these
errors as there is little it seems we can do about them and we therefore
choose to ignore them rather than fail the builds.
[YOCTO #8245]
There is a better solution proposed in the bug with a -1 timeout however
this avoids failed builds until such times as that is implemented.
