As discussed here:
https://lore.kernel.org/lkml/Z9RRkL1hom48z3Tt@google.com/
This code could benefit from some more commentary.
To avoid needing to comment the same thing in multiple places (I guess
more of these SKIPs will need to be added over time, for now I am only
like 20% of the way through Project Run run_vmtests.sh Successfully), add
a dummy "skip tests for this specific reason" function that basically just
serves as a hook to hang comments on.

It seems that 9pfs does not allow truncating unlinked files, Mark Brown
has noted that NFS may also behave this way.
It doesn't seem quite right to call this a "bug" but it's probably a
special enough case that it makes sense for the test to just SKIP if it
happens.

Conform the layout, informational and status messages to TAP. No
functional change is intended other than the layout of output messages.
Minor cleanups have also been included.

Rename selftets/vm to selftests/mm for being more consistent with the
code, documentation, and tools directories, and won't be confused with
virtual machines.
