nodejs*: drop nodejs{5,7,9}

[yan12125]

Description

Those versions are non-LTS and have reached their end-of-life [1].

Closes: https://trac.macports.org/ticket/53799
Closes: https://trac.macports.org/ticket/54083
Closes: https://trac.macports.org/ticket/55655
Closes: https://trac.macports.org/ticket/55656

I don't think there's a node.js package compatible with a non-LTS version but none of LTS versions. I don't touch nodejs 4 as newer nodejs versions does not work on 10.6 [2].

If you wouldn't mind terribly, I would appreciate a few days to see which of these is the actual latest version that 10.6.8 can support.

So much has changed with the legacysupport PG and libc++ that these older ideas of what is compatible with what might no longer be actually true...

Sorry, I don't have enough disk space to maintain a 10.6 VM :(

[kencu]

looks like many of the even numbered maintenance versions do build on older systems, so feel free to bin these defunct versions from my point of view.

Maintainer timeout! I also agree with removing non-LTS versions, so I'm going to merge this now. Thanks for your contribution.

Thanks for looking into this PR. With awesome efforts in #4119, I guess nodejs 4 can be dropped, too. Will do that in another PR.
