pkg/mount: simplify ensureMountedAs

Browse source 
1. There is no need to specify rw argument -- bind mounts are
   read-write by default.

2. There is no point in parsing /proc/self/mountinfo after performing
   a mount, especially if we don't check whether the fs is mounted or
   not -- the only outcome from it could be an error from our mountinfo
   parser, which makes no sense in this context.
