Fix Vscale hostedzone

[kuk]

In case of >1 domains "{.*\"name\":\s*\"$h\".*}")" matches {id: 1, name: a}, {id: 2, name: $h} that leads to wrong id (we look for id=2, but match id=1)

{[^{]*\"name\":\s*\"$h\"[^}]*} matches just {id: 2, name: $h}

@Neilpang could you please take a look at this PR. Currently Vscale DNS integration is broken, this PR fixes it

[Neilpang]

there can be more graceful fixes, for example:

echo  '{id: 1, name: a}, {id: 2, name: $h}' | tr "{" "\n" | grep "\"name\":\s*\"$h\".*}"

Split the text into multiple lines before greping them.

Because grep "[^{]" is not always safe on all the platforms.

Thank you, changed the code
