Ed Santiago b7147afde9 e2e tests: SkipIfRemote(): add a reason
Now that Dan has added helpful comments to each SkipIfRemote,
let's take the next step and include those messages in the
Skip() output so someone viewing test results can easily
see if a remote test is skipped for a real reason or for
a FIXME.

This commit is the result of a simple:

   perl -pi -e 's;(SkipIfRemote)\(\)(\s+//\s+(.*))?;$1("$3");' *.go

in the test/e2e directory, with a few minor (manual) changes
in wording.
