Allow fifos
Some years back, there was a historical reason (lost to the mists of
time) for which we had problems if we allowed actual creation of fifos,
but so far as we know we don't expect any problems with them now,
and there's a bitbake change which would like to be able to use fifos
for logging, so let's try enabling them and see what happens.
