create a table instead of an array to hold the fibers in pmap-full

[mraveloarinjaka]

There is a crash when using pmap-full because the list of fibers passed to "join" is an array and not a table.
The fix aligns pmap-full implementation to pcall.

error: bad slot #0, expected table, got <array 0x600002C65C40>

That does look like a mismatch.

Using tabseq seems better and it's what pcall (which also uses join) does -- perhaps that's something that motivated the specific proposed changes :)

Just spelling things out here for other reviewers.

Hello,
What are the next steps?
It is not clear whether I should amend the changes or if I am missing something.

My earlier comment was just saying that the proposed changes looked on the ok side. Sorry if that was unclear.

I think this PR and some others are awaiting the main maintainer's availability -- AFAIU he is pretty busy.
