Certiain udev entries might be of a size that makes libudev emit EINVAL
which right now leads to udevEventHandleThread exiting. Due to no more
handling events other elements of libvirt will start pushing for events
to be consumed which never happens causing a busy loop burning a cpu
without any gain.
After evaluation of the root cause of the example case discussed in
in #245 and a test run ignoring EINVAL it was considered safe to add
EINVAL to the ignored errnos to not exit udevEventHandleThread giving
it more resilience.
Fixes: #245
