runtime: Pass --thread-pool-size=1 to virtiofsd

Browse Source 
Dave Gilbert brough up that passing --thread-pool-size=1 to virtiofsd
may result in a performance improvement especially when using
`cache=none`. While our current default is `cache=auto`, Dave mentioned
that he seems no harm in having it set and he also mentiond that it may
use a lot less stack space on aarch/arm.

Fixes: #943
