libcontainer/specconv/spec_linux: Add support for (no)lazytime 

And also silent, loud, (no)iversion, and (no)acl.  This is part of
catching runC up with the spec, which punts valid options to mount(8)
[1,2].

(no)acl is a filesystem-specific entry in mount(8), but it's
represented by a MS_* flag in mount(2) so we need an entry in the
translation table.
